Stardates Explained - 20101203.0014

You don't understand the startdates?

Take, for example, 20101203.0014

Let me stick some spaces in some helpful places:

2010 12 03 . 00 14

That better?

20101203 means 3rd December 2010, and 0014 is in 24-hour clock format, IE 12:14AM

Stardates in the Star Trek universe work in an entirely different way. Wikipedia has a good explanation on how Stardates work.
