delay >60 sec handled not correct

In the run options of a job can specified setbacks. The delay for the setback should define in the format hh:mm:ss.
If seconds > 60sec specified the editor will accept 59sec in any case (the rest will be ignored).

The delay declaration like this accepted from the kernel (and can not declare via the GUI):
<delay_order_after_setback is_maximum="no" setback_count="1" delay="120"/>

delay="120" means a delay for 120 seconds.
