I'm a bear of very little brain today but I still don't see this... If the original zone is +1:00 and my zone is -4.00 adding them up gives me -3:00 which isn't right... If I ignore the sign it works out to +5:00 (which is "correct" in that it's the offset needed to convert the source zone to the target zone). But then if the original zone is -4:00 and the target zone is -5 I get either 9:00 or -9:00. I'm just not seeing how adding up the offsets does it... I know this is something that should be immediately obvious... but I'm just not having that light-bulb moment here. I think I'll just do the interim conversion for now... but it still seems like there must be a simple formula for this. > > Ah well... that'll work.
