Can you explain why they were added? I did not find any evidence of the existence of events "Ruthenia used CET 1990/1991" (comment in tz database).
As I recall, they were added because Shanks's International Atlas had them. The "europe" file says: # Unless otherwise specified, the source for data through 1990 is: # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), # San Diego: ACS Publications, Inc. (2003). # Unfortunately this book contains many errors and cites no sources. It's quite possible that Shanks was wrong, or that I transcribed Shanks incorrectly. If so, it'd be helpful to provide evidence of the error, so that we can fix tzdb.
