如何在特定时间设置Crontab？

Question

I'd like to set my Cron job to work at specific hour. Particularly, I'd like to set it at 1PM and 7PM every day of the year. How can I do? I wrote two line like those below:

0 13 * * * /usr/bin/php path/myphp.php
0 19 * * * /usr/bin/php path/myphp.php

but nothing works fine! Can someone help me?

Answer 1

0 13,19 * * * /usr/bin/php path/myphp.php should work, check your log / user mail for errors.
