The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.6/static/functions-datetime.html Description:
Hi everyone, I would like to request a clarifying statement in the docs: https://www.postgresql.org/account/comments/new/9.6/functions-datetime.html/ Specifically, for the case of 'extract epoch', the docs state: "for date and timestamp values, the number of seconds since 1970-01-01 00:00:00 local time" I ran an experiment, importing a timestamp '2016-06-26 20:01:38' with default time zone 'localtime', which is AEST in my case. SELECT id, extract(epoch FROM not_before) FROM bla; -> 1466971298 Now I switch to timezone = 'UTC' in postgresql.conf. Confirming with SHOW TIMEZONE that I am now in the default UTC timezone in my session. Same query: -> 1466971298 In other words, it seems that the function extract(epoch from timestamp) considered the timestamp field to be in UTC in both cases. I find it hard to reconcile that with the docs. Am I misreading something or is that something that should be fixed in the docs? -- Sent via pgsql-docs mailing list (pgsql-docs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-docs
