this 1917 timezone map of the world seems to indicate that the russian empire had not implemented timezones based on the worldwide standard. There are no reason to think that a surviving Tsarist Russia would *not* have adopted the same timezones as the USSR. IF you want something different, maybe just have half-hours zone (as exist OTL) applied to governates which overlap some worldwide hour-based timezones.Does anyone have a map about how timezones in a (surviving) Tsarist/non-Communist Russia could have potentially looked like?
Thanks in advance!
