Stardates Explained - 20110215.1654

You don't understand the startdates?

Take, for example, 20110215.1654

Let me stick some spaces in some helpful places:

2011 02 15 . 16 54

That better?

20110215 means 15th February 2011, and 1654 is in 24-hour clock format, IE 4:54PM

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