You don't understand the startdates?
Take, for example, 20001110.1321
Let me stick some spaces in some helpful places:
2000 11 10 . 13 21
That better?
20001110 means 10th November 2000, and 1321 is in 24-hour clock format, IE 1:21PM
Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
