I have a cron job that's managed through plesk. I'm being told that it's being executed twice in a day, once at 5AM and once at 5PM, based on the email that's being received.
Here's the cron line:
0 4 * * * wget http://website.com/script.php
So obviously there's a daylight-savings issue; that's not a problem. But why is it running twice? I thought that the hour specifier was a 24-hour denomination. But it seems to be running at both 4am and 4pm server time.
Please note that I'm managing the cron job though a Plesk web admin panel. I did some googling, but I couldn't find anything about Plesk cron bugs or issues.
What is going on here?
