There’s deviations and some islands are a day ahead of where they’d otherwise be. And these move from time to time. Apia in Samoa is GMT+1400. Pago Pago, just a few miles away is GMT-1300. As I write this it is Fri Oct 30 at 4:37pm in Apia and The Oct 29 at 3:37 in Pago Pago. A limit of +/- 1200 is totally bogus. Time doesn’t work that way. Warner
