Pando,

I figured what 1/288 is for. It is 5/(24*60). But
this value is valid only if we assume job finished within
minute. If job takes more than One minute, next schedule
time will be incorrect.

e.g.
00:00 --> first Job (took 30 seconeds)
00:05 --> second job ( took 1 minute and 30 seconds).


so next time will be

00:11 -->third job

Is there a way to get next interval without using current
time?

thanks
