1.) "Enter 77." When Locke is in the Flame way back when, we see that DHARMA is supposed to enter "77" if a Hostile intrudes; we later see that this blows the whole thing up. Sayid (who DHARMA thinks is a Hostile) intrudes near the Flame... in the year 1977.
After this - when Sayid sees the top-secret plans for the Swan - DHARMA would want a self-destruct mechanism to prevent any more secrets from coming out. They'll probably come to realize that Sawyer and co. are intruders as well. Isn't the year a whole bunch of Hostiles fooled everyone a good code?
2.) In last season's Jin/Sun episode, they showed Jin flashbacks and Sun flash-forwards. At first, it seemed like it was just to manufacture a surprise ending for that episode. But think about it. Now Jin is literally stuck in the past and Sun is literally stuck in the future.
That episode separated Jin and Sun into different times (one flashback, one flash-forward) and now the story has literally separated Jin and Sun into different times (1977. 2007)
