Instead of depending on the user to enter the TZ, LAT,
and LONG, would it be possible to pick up this info
from the HomeCity in the built-in CityTime
application? (I don't know anything about the Palm OS
to know if this is doable, but it seems like you ought
to be able to!)
There is already the City Coordinates, TZ, and daylight
savings time info in CityTime. An additional plus, is
if the user flies to a different city, s/he can just
change the Home City and the Palm will have the new TZ,
LAT, and LONG without the user having to reenter it.
Since you can edit the City info, the user can put in
all the cities/locations that they may want.
