I recently bought a digital watch with a neat feature that allows me to swap
the main display time with the WT (world time).
At first, I thought it was a great feature and used it while on vacation. The
trouble is, I immediately needed a 3rd TZ (time zone) -- what my normal WT
is usually set at (work tends to follow me around).
Therefore, I promptly lost my home time setting anyway.
Now I just set the main display time when I travel to other TZs and don't
mess with this feature :(
Do you have a watch feature that you thought was useful until you tried it?
