The all-knowing, all-powerful invisible sky daddy is fully aware of all local times and He will begin the apocalypse accordingly. Do NOT Doubt HIM!
well then wouldn't you figure that anyone with at least a pea-sized brain full of logic would stand somewhere with one foot on one side of the date line and the other foot on the other side - that would certainly confound the Great Oz, and if nothing else, one half of your body could watch the other half get raptured.
Has there been a great migration towards some island in the Pacific?
also, there's some fascinating info here:
https://www.timeanddate.com/time/dateline.html
For instance, every day between 10:00 and 11:59 UTC, three different dates on the calendar are in use at the same time on Earth.
and countries have just eliminating dates from the calendar - so after the Republic of Kiribati gained independence from Britain it decided to skip January 1, 1995 in order to reorient its position relative to the date line. Now Kiribati is always the first country to enter the New Year.
And in 2011, in order to have better trade relations with NZ and Australia, Samoa changed its time zone by shifting the dateline removing December 30, 2011 from the calendar.
So perhaps we could avoid all this potential trouble by just removing whatever date is predicted as the Apocalypse. We can always reschedule it later as the 12th of Never. It could sort of be like Leap Year but a little funkier.
