From Tim Parenti (2014-07-03), per Oscar van Vlijmen (2001-08-25):
Asia/Yekaterinburg covers...
02	RU-BA	Bashkortostan, Republic of
90	RU-PER	Perm Krai
45	RU-KGN	Kurgan Oblast
56	RU-ORE	Orenburg Oblast
66	RU-SVE	Sverdlovsk Oblast

Note: Effective 2005-12-01, (59) Perm Oblast and (81) Komi-Permyak
Autonomous Okrug merged to form (90, RU-PER) Perm Krai.

Milne says Yekaterinburg was 4:02:32.9.
Byalokoz 1919 says its provincial time was based on Perm, at 3:45:05.
Assume it switched on 1916-07-03, the time of the new standard.
The 1919 and 1930 transitions are from Shanks.
