Ok so far so good.
BUT
How or what do I enter in the time zone cell if I want to subtract hh:mm (time zone change) from the d/mm/yyyy hh:mm.
say arrival cell returns 27/09/2007 0:00 (EST) then minus 2:00 for the east to west time zone change to read 26/09/2007 22:00 WST ??
West to east is or appears to be a doddle but it wont accept a -hh:mm
