- Mexico will no longer observe DST after 2022, except for areas
near the US border that continue to observe US DST rules.
On 2022-10-30 at 02:00 the Mexican state of Chihuahua moves
from -07 (-06 with DST) to year-round -06.
- Fiji will not observe DST in 2022/3.
For now, assume DST is suspended indefinitely.
- Simplify four Ontario zones.
