Scheduled job starting too late

[Rüdiger Kupper]

Binary package hint: gnome-schedule

Frequenty, "at" jobs (one-time jobs) scheduled with gnome-schedule do not start at the scheduled time, but several minutes too late. Today, I scheduled a job to start at 23:00 h. It did run at 23:08 h.

This may not be related to gnome-schedule, but rather to at/atd. I can't tell.

This is likely to be an at problem, what is the output of 'atq' after you have added a task ?

Hi Gaute, thanks for the quick reaction, and sorry for my late answer.
I have scheduled a task for today at 20.00h (record 1 hour of internet radio, my standard use case).

Output of "atq" and "at" looks like this:

ruediger@helge:~$ atq
81 Mon Dec 14 20:00:00 2009 a ruediger

ruediger@helge:~$ at -c 81
#!/bin/sh
# atrun uid=1000 gid=1000
# mail ruediger 0

thanks, gnome-schedule just adds an 'at' task - and as you see it has been scheduled correctly on 20:00, after that its up to 'atd' to start the task when it should. So as far as I can see this is an atd bug.

You could try creating a task that does:
date > /tmp/testtask (make sure all output is on)

then check whats in /tmp/testtask.. is the time you are checking against the time on the server? are you sure they are synced?
