You don't understand the startdates?
Take, for example, 20101204.0937
Let me stick some spaces in some helpful places:
2010 12 04 . 09 37
That better?
20101204 means 4th December 2010, and 0937 is in 24-hour clock format, IE 9:37AM
Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
