Stardates Explained - 20171108.0058

You don't understand the startdates?

Take, for example, 20171108.0058

Let me stick some spaces in some helpful places:

2017 11 08 . 00 58

That better?

20171108 means 8th November 2017, and 0058 is in 24-hour clock format, IE 12:58AM

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