In the below example, we have selected timestamp with timezone for the date of 2020-07-01 19:10:25. where p is an optional precision specification giving the number of fractional digits in the seconds field. Your question makes more sense following your edit, but the fundamental problem remains. PostgreSQL: Documentation: 15: 8.5.

Looking for job perks? If you see anything in the documentation that is not correct, does not match Looking for job perks? For formatting functions, refer to Section9.8. The time-of-day types are time [ (p) ] without time zone and time [ (p) ] with time zone. Valid input for the time stamp types consists of the concatenation of a date and a time, followed by an optional time zone, followed by an optional AD or BC. Postgresql: how to correctly create timestamp with timezone from Side note: all events (including expiration stamps, like what you have here), should be stored "ignorant" about timezones/offsets. Converts given time stamp without time zone to time stamp with time zone, assuming the given value is in the named time zone. When the input value is of type timestamp with time zone, the truncation is performed with respect to a particular time zone; for example, truncation to day produces a value that is midnight in that zone. (See Section8.5.1 for how this setting also affects interpretation of input values.) Date is 2018-03-24 (Date of DST switch in this timezone). For example, to_timestamp(?, 'yyyy-mm-dd hh24:mi:ss Z'). The interpretation of postgres is to see it in the -08 timezone. Here's what happens if I change the timezone of the input timestamp.
