Run a cron script at 1:00 PM UTC every day

Question

i need to run a cron at 1:00 PM UTC every day, is this the right crontab for UTC ?

0 1 * * *

Answer 1

否，应采用24小时格式，因此

0 13 * * * 

Answer 2

The timezone within which cron jobs are scheduled by default, is based upon the default system timezone (/etc/timezone). Depending upon your distribution, you may be able to set CRON_TZ in your crontab.

If your system default timezone is UTC then 0 1 * * * is correct.

You can add a job like the following to your crontab to determine which timezone cron is using:

0 * * * * date > /tmp/date.out
