timzones

[Grant Byers]

Hi John,

Great patch!

One thing we really struggle with at my place of work is timezone 
support. Ideally, we'd love to be able to run one instance of nagios, 
supporting multiple timezones. I have seen people raise the issues & 
concerns associated with adding timezone support into the scheduler, 
particular for those timezones supporting daylight savings (ie; what 
does the scheduler do when we skip foward an hour at beginning of DLS, 
or skip backwards an hour at the end, how should times be displayed in 
the CGI interface etc.). I think these can have acceptable solutions, 
behaviour dependant on configuration options (ie. may be configured to 
either run anything that may have been missed when forwarding an hour, 
run a check twice when moving backwards an hour, or to ignore, display 
timezone offset in CGIs). Your patch at least introduces partial 
support, but IMHO would need to be configurable for these circumstances.

Thoughts, suggestions?

Regards,
Grant
