I once flew from Georgetown, Malaysia to Medan, Sumatra (Indonesia). The flight time was 30 minutes. The time zone in Medan was 30 minutes behind Georgetown so our arrival time was listed as being identical as the departure time.
Maybe this is more common than I think. I guess you would just have to take say a 3 hour flight across 3 time zones.
I’ve flown from Denpasar on Bali to Yogyakarta (pronounced Jogjakarta) on Java, which is one hour and crosses a time zone. Take off and land at the same time.
Last time i flew from Sydney, Australia to San Francisco, California, the plane departed at about 2.30 p.m. on Tuesday afternoon, and arrived at about 11.00 a.m. on Tuesday morning.
Of course, going the other way it’s a different story. Depart the west coast of the US on a Tuesday night, and arrive in Australia on Thursday morning. Where did Wednesday go?
I’ve flown from Atlanta to Birmingham, Alabama before, and I arrived 15 minutes before I took off. The flight is 45 minutes, and it crosses a time zone.
This was years ago, but I know someone who had a flight from Boise to Portland that did this, to the minute. Did a quick check online, seems that most direct flights nowadays are listed as being about 1:20 long, so :20 clock time. Probably have to schedule more time due to PDX being a busier airport now.
Its a different country, but the distance is so little that they made it only a half an hour time difference.
Nowadays they are a full hour apart.
However, not all places on an even hour’s time, GMT
Some places/countries use time offsets not an integral number of hours from UTC/GMT.
Examples:
Newfoundland (Canada) is UTC/GMT - 03:30 (summer -02:30)
Australia (Northern Territory) is +09:30
Australia (South Australia) is + 09:30 (summer +10:30)
India is +05:30
Iran is +03:30 (summer +04:30)
Afghanistan is +04:30
Burma (Myanmar) is + 06:30
Marquises Islands is - 09:30
Norfolk Isl. (Australia) is +11:30
Lord Howe Island (Australia) is + 10:30 (summer +11:00)
Sri Lanka is +05:30
Some places use quarter / hour offset from UTC/GMT.
Examples:
Nepal is UTC/GMT +05:45
Chatham Island (New Zealand) is UTC/GMT + 12:45 (summer UTC/GMT + 13:45 or winter in the northern hemisphere).
Western Australia, Eyre Highway towns: Eucla, Caiguna, Madura, Mundrabilla and Border Village (South Australia) use UTC/GMT +08:45
