Thanks, that's interesting. Decree No. 59 says this:

Первого апреля 1919 года в среднюю Гринвичскую полночь часы в каждом из поясов 
России поставить так, чтобы они показывали целое число часов, равное номеру 
пояса. Время в течение суток считать от 0 до 24 часов, принимая за начало суток 

which Google Translate renders as:

On April, 1919, in Greenwich Mean midnight hours in each of the Russian zone to 
put so that they showed a whole number of hours equal to the zone number. Time 
during the day to count from 0 to 24 hours, taking the start of the day at midnight.

I interpret this to mean that all Russian zones were supposed to switch to the 
new system at 00:00 GMT on the specified date (April 1 in that decree, but 
delayed to July 1 in Decree No. 147). Of course this would affect only the 
territories actually controlled by the Bolsheviks at the time. (Also, of course 
the actual switches were not implemented precisely; there was a war going on, 
after all.)

Proposed patch attached, and installed into the experimental repository on Github.
