Nagios disfunctional , perhaps due to time change ?

[Menard, Chris]

When we run into this in the US, what is the easiest way to correct the issue if we don't need to retain and downtime, acts or any status data.  Is there a file or two that just needs to be deleted?

Thanks,
Chris

Hi,

this change is causing the wrong reschedule:
http://nagios.cvs.sourceforge.net/viewvc/nagios/nagios/base/utils.c?r1=1.236&r2=1.237&view=patch

It has been applied on 15th of January 2009 and introduced some
statements

t->tm_isdst=-1;

into base/utils.c.

Affected are all Nagios versions >= 3.1.0.

I could reproduce it here: if the patch above is backed out, the
scheduling behaves correctly.
