Ok here is what I found in st3 source book update on the stardate thing.
Referance stardate
Because the startdate used in the TV series are not in sequence, they are not usefull for showing how long it has been since Captain Pike commanded the Enterprise, for instances. All new FASA productswill use a system of Refferance Stardates to messure time. they will pass at a regular rate, as messured from the communications beacon at the cinter of Federation space. They will form a sort of Greenwich mean time' for events important to Star Trek history' and FASA will use them in placing events in the timeline they develop for their adventures and supplements.
The numbering systemfor Referance Stardates is the same as that given above, with one exception. A number followed by a slash will allways preceed the standard stardate to show the century. The referance Stardating system will begin with 0/0001.01 meaning january 1,2000 thus, 1/0001.01 is exsactly 100 years after (January 1,2100), and -1/0001.01 is exactly 100 years earlier (January 1,1900). The refferance Stardate fr July 4,1776, is -3/7607.04, and so on.
so there you go hope it helps, ill still look thru all the rest for more info.
