You don't understand the startdates?
Take, for example, 20100406.2350
Let me stick some spaces in some helpful places:
2010 04 06 . 23 50
That better?
20100406 means 6th April 2010, and 2350 is in 24-hour clock format, IE 11:50PM
Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
