Thanks again. I installed the attached patch to correct the older Belize data from Shanks. I left the 1973/1974 and 1982/1983 transitions from Shanks as-is, as we don't have citations for that period. I just now checked, and Chris Pearce's book "The Great Daylight Saving Time Controversy" (2017) also says that there were transitions in Belize in 1973/1974 and 1982/1983, though he gives no details about dates and times. Pearce also mentions British Honduras newspaper reports from the 1950s that agree with the legal citations you gave, so that's a good sign.
