Calendar boundary
Check the date, not just the hour
At 09:00 in London, Auckland is on the same calendar date.
Daylight saving time
The gap can move during the year
Seasonal clock changes alter the gap: it is 13 hours ahead on the January reference date and 11 hours ahead on the July reference date. Transition weeks can differ again, so check the exact date.
