Stewart,

I reread your message and realized I misinterpreted it the first  
time. If I understand correctly, you want something to happen only  
during a specific time window. Here is one possible approach (not  
tested).

Let's say you want the handler to be triggered during some five  
minute window starting at a time you specify in field "openWindow".  
So this field may have, say, "11:30 AM" in it. So in your card script  
you might have:

local tStart, tEnd

on loadEventTrigger
   put fld "openWindow" into tStart
   convert tStart to seconds
   put tStart + (5 * 60) into tEnd
   checkWindowOpen
end loadEventTrigger

on checkWindowOpen
   get the seconds
   if it > tStart and it < tEnd then
     # do stuff here
   else
     # if not in the window, keep checking
     send checkWindowOpen to me in 1 second  # or whatever interval  
you want
   end if
end checkWindowOpen

Don't forget a way to cancel the pending message in case you leave  
the card. See the cancel command in the Dictionary.

HTRH,

Devin
