In SQL Server the GETDATE function returns the current date and time with milliseconds precision without the time zone for the current database instance.
In PostgreSQL you can use the NOW function but it includes time zone.
SQL Server:
-- Get the current date and time with milliseconds precision SELECT GETDATE(); # 2024-07-28 13:13:11.640
PostgreSQL:
-- Get the current date and time SELECT NOW(); # 2024-07-28 13:13:11.640768+03
