summer time

Hi All,
this week end the time's going to switch off summer time modality.
What will it happen to cron daemon?
I was thinking scheduling a script at 2.59 which contain a "sleep 61" command and then a restart of cron daemon.
What do you think about this idea?
Is a workaround exist?
Thanks to All.
BR,
i.

Re: summer time

Ivan,

Cron is designed to handle these transitions without problem. Take a look at the man page for cron, in particular the section "Spring and Autumn Time Transitions".

Re: summer time

No need to restart cron, or do anything.
Commands scheduled to run at "ambiguous time" (ie time that occurs again after the clocks go back) only get run once.

See the "Spring and Autumn Time Transitions" section within man cron.

See also man 4 tztab.
