   Jake tapped his hands on the sides of his food tray. "So humans and Klingons are
   missing?"
   Bashir shrugged and turned off his padd. "There's a lot they aren't telling us
   about what's going on."
   Intriguing to Bashir, Jake immediately dropped his eyes to his collection of
   reconstituted rations and busily began peeling off their clear tops. When he had
   first visited the mess hall, Bashir had been interested to notice that what he
   thought were replicator slots lining one wall were actually small transporter
   bays with a direct connection to a food-processing facility a few kilo-
   meters away. Replicator circuitry and power converters were considered a
   critical resource and used for only the most important manufacturing needs.
   "So, how's Nog?" Bashir asked, trying to keep his tone innocuous, but wondering
   why Jake had chosen not to react to his statement. He took a sip of the tea he
   had requisitioned. It was too cold, too sweet, and tasted nothing at all like
   tea.
   "Different," Jake said, frowning at the contents of the containers he had
   uncovered. Again, it was not clear to Bashir if the frown was directed at the
   food or at his question.
   'To be expected, don't you think?"
   Jake gingerly dabbed a finger into the red sauce that covered a brownish square
   of... something, then tentatively licked his finger. He grimaced. "I actually
   miss the combat rations on the Augustus."
   Bashir smiled in commiseration. Vulcan combat rations were logical and not much
   else. They consisted of tasteless extruded slabs which were mostly vegetable
   pulp compressed to the consistency of soft wax. Accompanied by packets of
   distilled water and three uncomfortably large supplement pills to compensate
   for the differences between Vulcan and human nutrient requirements, 500 grams
   of pulp were sufficient to maintain a normal adult body for thirty hours.
   Vulcans were proud of the fact that their rations only had to be ingested once
   a day, and that the process could be completed in less than two minutes. How
   much more efficient could eating become? All of the temporal refugees had lost
   body mass during their voyage on the Augustus.
   It was also possible, though, that Jake's joke might
   have another purpose—to change the subject. Bashir didn't intend to let such a
   ploy go unchallenged.
   "Were you having an argument with Nog?" he asked. "Before we all had dinner at
   the Starbase?"
   He saw the answer in Jake's guilty expression. "Jake, it's bad enough that
   Starfleet is keeping secrets from us. We can't keep them from each other, too."
   Bashir dropped his own voice to a near whisper. "What did he tell you?"
   Jake's shoulders sagged. "It's more what he didn't tell me... tell us."
   "About what?"
   Jake dropped his napkin over his untouched food. "He was lying to us."
   Bashir felt the unwelcome touch of alarm. He had considered that possibility
   himself. "About the Phoenix?"
   "No... I don't think about all that. Like, the Phoenix and going back
   twenty-five thousand years and the deep-time charges in B'hala... I really think
   that's what Starfleet's planning. Or was planning. But... when he told us he had
   no doubt that the mission would succeed ... that was a lie."
   Bashir put down his pad. "Considering the rather audacious nature of the
   mission, I'm not really surprised. It's perfectly understandable that Nog might
   harbor some doubts about the possibilities for success."
   But Jake shook his head emphatically. "I'm not talking about doubts. Or being
   nervous. I mean ... look, it's as if Nog already knows the mission can't
   succeed."
   "Did he say that to you? Is that what you were arguing about?"
   Jake looked right and left,, obviously concerned about anyone overhearing their
   discussion. "That was part of it. But he didn't have to tell me. Not flat out."
   "I don't understand."
   Jake shifted uncomfortably. "He's been my best friend for... well, we were best
   friends for a long time. And I can tell when he's lying. He does this thing with
   his eyes and... his mouth sort of freezes in position."
   Jake was obviously developing some skill in observation. "They call it a
   'tell.' Or they used to," Bashir corrected himself, "a few centuries ago. In
   gambling and confidence games, some people develop a nervous habit which gives
   away the fact that they're bluffing. You're very observant."
   Jake shrugged. "Not really. Uh, Nog sort of told me himself. His father and
   uncle kept giving him a hard time about it. They, uh, they claimed he had picked
   it up from me... a filthy human habit that would hold him back in business."
   Jake smiled weakly. "He tried to run away from the station a couple of times."
   "I didn't know," Bashir said truthfully.
   "I... talked him out of it. But anyway, he's still doing it. And he was
   definitely lying to us."
   Bashir sat back in the flimsy mess-hall chair and mentally called up a Vulcan
   behavioral algorithm to try to calculate the odds that Jake was correct in his
   conclusion of Nog's truthfulness. Once the Vulcans had realized the failure of
   their early predictions that any species intelligent enough to develop warp
   drive would of course have embraced logic and peaceful exploration as the
   guiding principles of their culture, they had developed complex systems for
   modeling and predicting alien behavior as a form of self-survival. It was a
   difficult set of equations to master, but one could always count on a Vulcan to
   figure the odds for just about any eventuality.
   Bashir completed his calculations. In the limited way
   he had trained himself in the Vulcan technique, he was forced to conclude that
   given the relationship between Jake and Nog, Jake was more likely than not
   correct in his assessment of his friend. Since there was nothing to be gained
   from questioning Jake's conclusion, the only logical course was now to determine
   the underlying reasons for Nog's behavior.
   Bashir began the requisite series of questions. "Did you tell him that you knew
   he was lying?"
   Jake nodded. "That's when he got mad at me."
   "But did he deny lying?"
   "How could he?"
   "Did he say why?"
   Jake appeared to be more profoundly unhappy than Bashir ever recalled seeing him
   before.
   "All he told me was that I should keep my... my ridiculous hew-mon opinions to
   myself. And then, well, he sort of let me know that it was really important that
   I not tell anyone what I thought."
   "With what you know of him, Jake, is there any reason you can think of why Nog
   would lie to us about the success of the mission?"
   Now Jake looked positively haunted. "I... I think so."
   Bashir leaned forward to hear Jake's theory about how Captain Nog was really
   going to save the lives of the temporal refugees—and the universe.
   And what he heard was utterly fascinating, and at the same time utterly
   horrifying.
   CHAPTER 14
   "You know how Stardates work," Commander Arla Rees said.
   "Of course." Sisko nodded, distracted, wondering about what was beyond the
   windowless hull of t
he small travelpod they were riding in. It reminded him of a
   two-person escape module, though he could see no indication that it carried
   emergency supplies or even flight controls. According to Weyoun, transporters
   were not permitted to operate anywhere within the Bajoran system—though he had
   provided no explanation why— and all travel here was carried out by pod,
   runabout, or shuttle. Thus, the survivors from the Defiant had been sent off
   from the Boreth's hangar deck two by two, in these tiny pods with no means by
   which to observe the somehow restored Deep Space 9 as they neared it.
   "Seriously?" Arla persisted. "You've actually looked into how the Stardate
   system was devised?"
   Sisko looked across the cramped pod—or down the pod, or up it. There was no
   artificial gravity field, and no inertial dampeners either. Essentially, he and
   the commander were the only passengers in a gray metal can with two acceleration
   seats with restraint straps, a pressure door, and four blue-white lights, two at
   their feet and two at their heads. Sisko even doubted if the simple vessel had
   its own engines or reaction-control system. He guessed they were being guided
   from the Boreth to DS9 by tractor beam.
   "I've studied timekeeping."
   Arla frowned. "When? They don't tell you a lot in the Academy."
   "Actually, I had reason to take an extension course a few years ago. I even
   built a few different types of mechanical clocks on my own." Sisko tried to
   lean back in his acceleration seat, but of course there was no gravity field to
   aid his maneuver—only the two chest-crossing straps that kept him from floating
   out of the seat.
   "Did your course deal with how the system got started?"
   "Some of it. As I understand it, Commander, the impetus behind devising a
   universal—or, at least, a galactic—standard time- and date-keeping system was
   primarily religious."
   From her seat beside him, Arla nodded her head in agreement, though Sisko didn't
   understand the reason for the odd smile that accompanied that nod.
   He continued, not knowing what she was looking for in his answer. "There's
   certainly precedent for it. Many of the religious festivals and holy days
   celebrated on Earth are tied to the calendar."
   "More often than not the lunar calendar, I believe," Arla said.
   "That's right," Sisko said. Though he still didn't know why they were having
   this conversation, it seemed harmless enough. He decided to run with it The
   commander would give him her reasons when she was ready, and mat was fine with
   him. "Now if my memory serves me right, when the first outposts were set up on
   Earth's moon, since everyone lived underground and the moon is less than a
   light-second from Earth, timekeeping wasn't a problem. But when the outposts on
   Mars were established, and it was common for people to spend years mere with
   their families, I recall learning mat it became awkward trying to reconcile
   Martian sols at twenty-four-and-a-half hours with Earth days at just under
   twenty-four. So a council of religious scholars on Mars came up with the first
   Stardate system—Local Planetary Time—based, I believe, on the look-up tables and
   charts the Vulcans had been using to reconcile their starships' calendars with
   their homeworld's."
   "The Vulcan system was based in philosophy," Arla said, as if making some
   important point, "not religion."
   "I... suppose you could say that," Sisko said amiably. "Now, for most people,
   once you have a few thousand starships and outposts and a few hundred colonies,
   it gets too cumbersome to keep using look-up tables and charts. But," Sisko
   smiled, "not for Vulcans. It's no secret they have no problem keeping forty or
   fifty different calendar systems in their heads at the same time. But humans,
   we freely admit, tend to place more cultural and religious importance on
   specific days."
   "Just like Bajorans," Arla said as she turned to him, her eyes filled with a
   passion Sisko didn't recall having
   noticed before. She then paused expectantly, as if she had still not heard what
   she needed to hear.
   "Is there some point to this conversation?" Sisko finally asked.
   But Arla's answer merely took the form of another question. "What happened next?
   According to the extension course you took."
   Sisko sighed, tiring of their exercise. He wondered how long it would take for
   the pod to drift over to the station. He was surprising himself with his need to
   touch the metal walls and feel the decks of DS9 beneath his boots again. And
   with his desire to have someone tell him how it was that he could have seen DS9
   destroyed, and yet see it now restored. Weyoun had been of little help. All he
   would answer in reply to Sisko's questions was, 'In time, Benjamin. All will be
   explained in time."
   Only because there was absolutely nothing else to do at the moment, Sisko
   continued to humor Arla. This time his answer came straight out of the Academy's
   first-semester text file. "The underlying principle of the universal Stardate
   system is that of hyperdimensional distance averaging."
   "Which is?"
   Sisko grimaced. The last time he had had this basic a conversation with anyone
   about Stardates, Jake had been five and sitting on his knee, struggling to get
   bis Plotter Forest Diary program to work on the new padd Sisko had given him for
   his birthday.
   "If you insist" Sisko then rattled off the requisite information. "Any two
   points in space can be joined by a straight line. The length of that line,
   divided by two, will yield the midpoint. If the inhabitants of both points
   convert their local time to the hypothetical time at the
   midpoint, then they both have an arbitrary yet universally applicable constant
   time to which they can refer, in order to reconcile their local calendars." He
   paused before continuing. "You know, of course, it's the exact same principle
   developed on Earth when an international convention chose to run the zero
   meridian through Greenwich, establishing Greenwich Mean Time. It was a
   completely artificial standard, but a standard everyone could use."
   "And...," Arla prompted.
   "And," Sisko sighed. The Bajoran commander's persistence was fully up to Vulcan
   standards. "Any two points can be joined by a straight line. Go up a dimension,
   and any three points can be located on a two-dimensional plane. Go up another
   dimension, and any four points in space can be located on the curved surface of
   a three-dimensional sphere. Any five points can be found on the surface of a
   four-dimensional hyper-sphere, and so on. The standard relationship is that any
   number of points,«, can be mapped onto the surface of a sphere which exists in n
   minus one dimensions. And that means mat all of those points are exactly the
   same distance from the center of the sphere. So, just after the Romulan War, the
   Starfleet Bureau of Standards and the Vulcan Science Academy arbitrarily chose
   the center of our galaxy as the center point of a hypersphere with... oh, I
   forget the exact figure... something like five hundred million dimensions, okay?
   So theoretically, every star in our galaxy�
�along with four hundred million and
   some starships and outposts—can be located on the surface of the hypersphere and
   can directly relate their local calendars and clocks to a common standard time
   that's an equal distance from
   everywhere. Just as everyone on Earth used to look to Greenwich." Sisko gripped
   his restraints and pushed himself back into his acceleration couch, trying to
   compress his spine. The microgravity, not to mention his traveling companion,
   was giving him a pain in the small of his back, as his spine elongated in the
   absence of a strong gravity field. "Is that sufficient?" he asked sharply.
   "What do you think?" Arla replied.
   A sudden shock of pain pulsed through Sisko just above his left kidney. He
   remembered the sensation from his microgravity training decades ago in the
   Academy's zero-G gym. He forced his next words out through gritted teeth. "I
   think it's a damn simple system. One that works independent of position and
   relativistic velocity. And since it's based on the galactic center it's
   blessedly free of political overtones." Sisko smiled in relief as his back spasm
   ended, as suddenly as it had begun, and as he at the same time relived a sudden
   memory of the one sticking point Jake—like most five-year-olds—had had when it
   came to learning Stardates. "And once a person gets used to the idea that
   Stardates can seem to run backward from place to place, depending on your
   direction and speed of travel, it becomes an exceedingly simple calculation to
   convert from local time to Stardate anywhere in the galaxy.
   "So—if you're asking me if I'm in favor of Stardates, Commander, yes, I am. Now
   what does this have to do with anything?"
   Arla's expression was maddeningly enigmatic, and Sisko could read no clues in
   it. "So you consider the system to be completely arbitrary?"
   "Any timekeeping system has to be. Because the uni-
   verse has no absolute time or absolute position. Now would you please answer my
   question."
   "Then how is it—" Arla said, and Sisko's attention was caught by her tone. The
   commander was finally ready to make her point. "—nine days from now, when the
   two wormholes are going to open in the Bajoran system only kilometers apart from
   each other and... and supposedly end the universe, or transform it somehow,
   that that completely arbitrary Stardate system is going to roll over to 7700.0
