You don't understand the startdates?
Take, for example, 20010129.1314
Let me stick some spaces in some helpful places:
2001 01 29 . 13 14
That better?
20010129 means 29th January 2001, and 1314 is in 24-hour clock format, IE 1:14PM
Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
