Now is a traditional PostgreSQL equivalent to transactiontimestamp. All the date/time data types also accept the special literal value now to specify the current date and time (again, interpreted as the transaction start time). Thus, the following three all return the same result. PostgreSQL – To modify the time zone for Amazon RDS PostgreSQL DB instances at the database level, set the value of the time zone parameter in a custom parameter group. The time zone parameter takes the input form of UTC-X or UTC+X. X is the number of hours that the time zone is offset from UTC time. at UTC is wrong because it takes now and says: if it were now time UTC what would it be here (timezone) and returns that. I want to return 'what time is it now in UTC?' Thanks in advance. /Kevin - Sent via pgsql-admin mailing list (pgsql-admin(at)postgresql(dot)org) To make changes to your subscription: http.
In this post, I am sharing a conversion statement which converts Timestamp into Milliseconds in PostgreSQL Server.
There are multiple reasons where we need milliseconds from the given Timestamp like comparing the timestamp value in number format for exact matching.
We can use EPOCH time format, to get the milliseconds from Timestamp.
Get milliseconds without specifying timezone:
Get milliseconds by specifying timezone:
SELECT EXTRACT(EPOCH FROM (SELECT NOW() AT TIME ZONE 'UTC')) * 1000;
