I asked this a year or two ago but haven't GM'd this system much since then and forgot.
How do I read time/date stamps in this game? For instance 817.M41
I think that means the year 41,817. Typically a more exact time/date format, such as 7252.777.M41, is also seen. I interpret that as the year 41,777. The first four numbers are thousandths of a year. So 0001.777.M41 would be the above year and roughly 8 hours, or January 1st, 0800 HRS, 41,777.
A present day example would be 0001.017.M2, this would be 0846 HRS 01JAN2017.
Is that accurate? A thousandth of a year (365.25 days) turns into 8.4596 hours. I rounded up the seconds.
