UTC is not a time zone. I cannot know what you mean and in which context. I can tell you to look here: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones which is the context for computer time, or TZ database time zones, where you may find Etc/UTC as time zone. I can tell that in the context of the PostgreSQL database, "UTC" is time zone, as following works well: SELECT current_timestamp AT TIME ZONE 'UTC'; timezone ---------------------------- 2023-02-16 14:13:37.837977 (1 row) SELECT CURRENT_TIMESTAMP; CURRENT_timestamp ------------------------------- 2023-02-16 17:13:42.709239+03 There are differen time zones' categories: https://en.wikipedia.org/wiki/Lists_of_time_zones In military context: https://en.wikipedia.org/wiki/List_of_military_time_zones It is called "Zulu Time Zone" or "Z" Then in this context: https://en.wikipedia.org/wiki/List_of_time_zone_abbreviations There is abbreviation "UTC" if you look there. So, yes I do agree that UTC is "not time zone", but I do not know in which context you mean. As in many common contexts the UTC is the time zone. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
