Alana, it is my understanding, too, that the swap will end at:
6:59:59 pm Eastern Time Zone (UTC -5) on January 12th
5:59:59 pm Central Time Zone (UTC -6) on January 12th
4:59:59 pm Mountain Time Zone (UTC -7) on January 12th
3:59:59 pm Pacific Time Zone (UTC -8) on January 12th
12:59:59 am Central European Time Zone (UTC +1) on January 13th ("Jonna Time"
)
I think that covers all the time zones of participants.
(The ATP server is on UTC time which means it keeps time as if it were a person living in Greenwich in London, England [when on regular GMT time and not on daylight-savings time.])
