Dear Tzdata Maintainers, Is it historically appeared in Asia, that several Locations have Offset only instead of Time Zone Abbreviation? I mean next location: Bangkok<https://www.timeanddate.com/time/zone/thailand/bangkok> from Thailand<https://www.timeanddate.com/time/zone/thailand> which is related with Vientiane<https://www.timeanddate.com/time/zone/laos/vientiane> from Laos<https://www.timeanddate.com/time/zone/laos> and Phnom Penh<https://www.timeanddate.com/time/zone/cambodia/phnom-penh> from Cambodia<https://www.timeanddate.com/time/zone/cambodia> - all of them is in Indochina Time<https://www.timeanddate.com/time/zones/ict>, but in repository for file asia they have only offset: https://github.com/eggert/tz/blob/main/asia#L3823 I don't know is it issue or typo, cause I didn't find any info when this Abbreviation was added https://en.wikipedia.org/wiki/UTC%2B07:00 For our customers, I added this step before compiling tzdata sources: # set Asia/Bangkok for Thailand to use name instead of digits in timezone, affecting on Asia/Vientiane for Laos and Asia/Phnom_Penh for Cambodia sed -i -e '/# Thailand/,/Vientiane/s/+07/ICT/' $(pwd)/asia but maybe it doesn't require and you will add corresponding changes in the main source code. BTW, during my investigation, I observed that several time zones have same behavior, ex.: Tajikistan<timeanddate.com/time/zone/tajikistan> - Asia/Dushanbe<https://www.timeanddate.com/time/zone/tajikistan/dushanbe> - TJT - Tajikistan Time<https://www.timeanddate.com/time/zones/tjt> https://github.com/eggert/tz/blob/main/asia#L3817 Turkmenistan<https://www.timeanddate.com/time/zone/turkmenistan> - Asia/Ashgabat<https://www.timeanddate.com/time/zone/turkmenistan/ashgabat> - TMT - Turkmenistan Time<https://www.timeanddate.com/time/zones/tmt> https://github.com/eggert/tz/blob/main/asia#L3834 United Arab Emirates<https://www.timeanddate.com/time/zone/united-arab-emirates> - Asia/Dubai<https://www.timeanddate.com/time/zone/united-arab-emirates/dubai> - GST - Gulf Standard Time<https://www.timeanddate.com/time/zones/gst> https://github.com/eggert/tz/blob/main/asia#L3839 Uzbekistan - Asia/Samarkand | Asia/Tashkent - UZT - Uzbekistan Time<https://www.timeanddate.com/time/zones/uzt> https://github.com/eggert/tz/blob/main/asia#L3851 Vietnam - Asia/Ho_Chi_Minh - ICT - Indochina Time<https://www.timeanddate.com/time/zones/ict> https://github.com/eggert/tz/blob/main/asia#L3920 Sri Lanka - Asia/Colombo - IST - India Standard Time<https://www.timeanddate.com/time/zones/ist> https://github.com/eggert/tz/blob/main/asia#L3645 Singapore - Asia/Singapore - SGT - Singapore Time<https://www.timeanddate.com/time/zones/sgt> https://github.com/eggert/tz/blob/main/asia#L3581 Saudi Arabia - Asia/Riyadh - AST - Arabia Standard Time<https://www.timeanddate.com/time/zones/ast-arabia> https://github.com/eggert/tz/blob/main/asia#L3565 Qatar - Asia/Qatar - AST - Arabia Standard Time<https://www.timeanddate.com/time/zones/ast-arabia> https://github.com/eggert/tz/blob/main/asia#L3518 Please give me explanation of this, is it correct to use Offset instead of Abbreviation or it will be fixed in future?
