Greetings from Ottawa Can somone confirm if the UNTIL & TO dates provided in the tzfiles are all Gregorian dates? In particular, I believe that Serbia & Russia switched from the Julian calendar to the Gregorian calendar in 1918, and Greece in 1923, yet some dates recorded in the tzfiles for these locations span their switch of calendars. There may also be a similar issue with Alaska. When processing historical zones before a locations's conversion conversion to Gregorian calendar, should I be interpretting the provded dates as Julian dates, or Gregorian dates?
