This may seem like a hoax, but here are the facts:
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.1317 installed on Thu Mar 27 09:39:37 2003)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
10 8 * * 1-5 cdplay
05 * * * * cjb.pl -s
Above is my crontab. As you can see, there is a cdplay job set to go off every weekday at 8:10, and a perl script ever day at five past the hour.
I don't know when the perl script goes off, but I can guarantee that the cdplay goes off AT 7:30 EVERY MORNING.
Has anyone ever encountered a case of cron doing that? going off 40 minutes early? (or 23 hours late, who knows?)
Any help is appreciated.
