Does grails / hibernate store Dates with milliseconds in PostgreSQL?

Question

I'm currently using grails with classes storing java.util.Date fields als DATETIME. However I need the precision / milliseconds to be stored as well which I think is not possible with MySQL.

If I switch to PostgreSQL, will it store my Dates with millisecond precision (or is it easy to configure it this way)?

Answer 1

Yes, since MySql 5.6.4 you can use DATETIME(3) for milliseconds, or DATETIME(6) for microseconds

TIME and other types also now support precision.

Answer 2

Yes, Hibernate / PostgreSQL can also store milisecond precision, no problem. Use the Hibernate timestamp datatype.
