I don't know if there is a better way to do this but what comes to  
mind first is to just create two different timeperiods and assign them  
to each contact. Assume one person and the nagios server are in CST  
and someone else is UTC --

define timeperiod{
        name                    workhours-cst
        timeperiod_name         workhours-cst
        monday                  09:00-17:00
        tuesday                 09:00-17:00
        wednesday               09:00-17:00
        thursday                09:00-17:00
        friday                  09:00-17:00
        }

define timeperiod{
        name                    workhours-utc
        timeperiod_name         workhours-utc
        monday                  14:00-22:00
        tuesday                 14:00-22:00
        wednesday               14:00-22:00
        thursday                14:00-22:00
        friday                  14:00-22:00
        }

You'd have to change the UTC guy 2x a year to deal with DST time  
changes if you honor that in your timezone. There are much more  
complex time definitions you could create that could deal with DST if  
you wanted.

Depends a lot on hardware you're running it on and the types of checks  
you are using. You'll hit some points where you'll probably need to  
change your way of doing things (i.e. at ~10,000 active checks you  
might need to start looking at moving those to passive checks), etc.  
There are others on the list running instances with many 10's of  
thousands of checks that might be able to offer insight into those  
kinds of things. If you expect to grow large, I'd recommend starting  
out with a simple distributed setup and expand as needed.
