You don't understand the startdates?
Take, for example, 20011110.1755
Let me stick some spaces in some helpful places:
2001 11 10 . 17 55
That better?
20011110 means 10th November 2001, and 1755 is in 24-hour clock format, IE 5:55PM
Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
