You don't understand the startdates?
Take, for example, 20261111.2007
Let me stick some spaces in some helpful places:
2026 11 11 . 20 07
That better?
20261111 means 11th November 2026, and 2007 is in 24-hour clock format, IE 8:07PM
Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
