Linux – What Time Zone Does a Cron Job Use

linuxPHPtimetimezone

I'm guessing there's a difference between my PHP time and the server time.

When I check the current time in PHP, it's showing that MST is being used. However, cron jobs aren't running at the correct time.

How can I check to see what timezone the server itself is using, not what PHP is set to use?

Cron job uses the server's define timezone (UTC by default) which you can check by typing the date command in terminal.

All countries timezones are defined in /usr/share/zoneinfo directory:

cd  /usr/share/zoneinfo/

When you cd into this directory you will see the name of different countries and their timezone.

Command to change server timezone.

sudo ln -sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime

If you live in America > LA you can change your time-zone using above command. Change the country and state according to your requirement.

Command to check the date and time:

 date

Set time and date from the command line:

date -s "19 APR 2012 11:14:00"
