Re: [NOVICE] Does pg store all `timestamp with time zone` inlocaltime? Why?

Threre's a really good explanation of the data type, it's implementation, usage and how to insert/select values:

(This was one of those "this is why I love Postgres" moments!)

No, it stores in UTC and converts back and forth as you store then in
and as you read them out.  It depends on the TimeZone configuration
parameter each time.  The TZ that was current when the value was stored,
is itself NOT stored in the same column.  You could add a column to
store that TZ, if you wanted.
