 Posted: Tue Jun 29, 2004 1:19 pm Post subject: the hour of vixie-cron |
 |
|
hey all,
this is somewhat strange, but i was wondering if there is some way to find out when a certain entry in my user crontab is running... reason being: if i make an entry like so,
| Code: | | 0 2 * * * /path/to/perl/script.pl arg1 arg2 |
this would mean that the script should run every day at 2:00am, correct? well, for some odd reason, it doesnt. however if i make the entry
| Code: | | 50 * * * * /path/to/perl/script.pl arg1 arg2 |
then it works running at 1:50, 2:50, etc...
so i just wanted to know if there is some other way that vixie gets its timing, because my system clock is set correctly with ntp-client, so i dont know what time vixie-cron is reffering to. unless there could be something else that would make the first "code" not run correctly?
i dont know. this is pretty new to me, but i was hoping vixie-cron just ran off the system clock. thanks for any help.
ps - these are all using 'crontab -e'
hmm... am i just not making sense? i just tried to set a crontab entry to run at '30 8 * * *' and it worked... but! it is 9:30am here! does that seem right??

map { $i++ while chop; push (@dune,$i); undef $i; } split /[eE]/;
map { print chr ${\(shift(@dune) + $_)}; } split /[DUNE]/,$japh;

That is correct, it should run at 2:00 am everyday.

It should run at 1:50, 2:50, etc, as you specified to run every 50th minute of every hour of every day.

You could add a crontab entry to log the current `date` to a log file to see what cron is seeing,
| Code: | | 0 2 * * * date >> ~/date.log |
For more information about crontab entries, see
