Change Google Cloud SQL CURRENT_TIMESTAMP time zon

问题:

I'm using CURRENT_TIMESTAMP in Google Cloud SQL and according to Google, it returns the server's current time.

Currently, with the time that it returns, it looks like the server's at UTC -1 (i.e., in the Atlantic Ocean). This is not very helpful.

How do I change the timezone and have it display the right time (i.e., a time zone of my own choosing) whenever I call CURRENT_TIMESTAMP?

Cloud SQL sets the system time as UTC.

You can set the timezone for an individual session with a statement like:

SET @@session.time_zone='-07:00';

You can use named (and daylight savings aware) timezones such as "US/Pacific" if you first set up the timezone table by running a system command like:

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -h YOUR_INSTANCE_IP -u root -p mysql
