I have yet to go looking for the new subforum--not sure where it is or if I'm in it already, :facepalm:
I don't recall seeing anyone mention this, but Mountain Bell more or less covered the Mountain Time zone. If on the east coast, the Mountain Time Zone is 2 hours behind. If in the Mountain Time Zone, there are no continental US time zones that are "3 hours less" (if you're in AZ during the summer (Daylight Savings Time is not observed, so they're basically on Pacific time), then the Hawaii Time Zone is 3 hours earlier).
I lean towards it being a very sloppy "13", which is (as another poster pointed out in the previous, 81-page thread
) the non-DST offset of time between Texas (UTC -6) and Thailand (UTC +7)... though Texas is not even in Mountain time, so IDEK :banghead:
Funny, that the possible "(13" almost looks like a "(B" to me... but "(B hours less)" makes even less sense... :banghead::banghead:
