Stardates Explained - 20101204.0937

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.
