If there is something amiss, please point it out.

If we think that the Ynnari and Celestians ventured in Ultramar around ~000.M42, we can count something of 800 ticks from the Gathering Storm 3 from "days" and "weeks since" "8th day" and similar, which Guilliman spent in Ultramar before he ventured on Terran Crusade.

So in Rogue Trader rulebook it is said that going from one end of the galaxy to another would take 85-510 months. As the jumps were short ones, I guess the max time is appropriate, so 510 months. From Ultramar to Maelstrom it is approx half-a-galaxy, so it would take 255 months
 * 1 month = ~29,5 days
 * 255m*29,5d = 7522,5 days
 * 1 day = ~24 hours
 * 7522,5d*24h = 180540 hours
 * one thousandth of a year is 365 days multiplied by 24 hours divided by a thousand
 * 365s*24h = 8760 hours and 8760h/1000 = ~8,7 hours
 * So one tick is 8,7 hours. Ticks being now numbers presented as X: 0.XXX.000.M00
 * So back a bit: 180540 hours divided by 8,7 ticks = 20751 ticks which makes 20 years and 751 ticks
 * and so it becomes X.750.019.M42 because the first number is not 1 but 0 (ie. 1st eight hours of the 1st year of the 1st millennium is x.000.000.M1 when in Julian and Gregorian calenders the first year is 1)

These are just approximates and you can get quite a significant differences in dates if you calculate dates with "different" years. But yeah. Approx 134. Sooner or later they'll give us a date and that is going to be closest. Remember that I said it ; D
