At the end of the 1800's countries started standardising time across the 
country, but switching to 'timezones' with hour offset did not happen 
until later. So in the case it reads as 1880 at least an area of Ukraine 
switched to an offset of '2:02:04' while Zaporozhye standardised on 
'2:20:40' and so on, then in 1924 the whole country standardised on a 2 
hour offset. What is missing from the comments in the Europe file is any 
corroborating evidence so the source of the actual dates is missing and 
it would be nice to see some Ukrainian input to fill in the gaps ...
