PostgreSQL – LOCALTIME Function

ByAdmin August 9, 2023August 9, 2023

In PostgreSQL, the LOCALTIME function is used to retrieve the current local time without the date component. It returns the current time in the time data type, which includes the hours, minutes, seconds, and fractional seconds.

The basic syntax of the LOCALTIME function is as follows:

SELECT LOCALTIME;

This query will return the current local time in the format HH:MI:SS.MS, such as 15:30:45.123456.

The LOCALTIME function is an SQL-standard function that should work in most PostgreSQL installations. However, in some versions of PostgreSQL, this function might be an alias for CURRENT_TIME. If you encounter any issues with LOCALTIME, you can use CURRENT_TIME as an alternative.

If you want to include the time zone information in the output, you can use the CURRENT_TIME function with the AT TIME ZONE clause.
