UTC−13:00

UTC−13:00 is an identifier for a time offset from UTC of -13:00 hours.

Towards the end of 2010s decade, this offset is now unused as ORBIT 1 & ORBIT 2 switched back to Asian date by skipping December 31, 2019. Previously, UTC−13:00, along with UTC−14:00, were the earliest time zones to greet New Year's Day.
