from time zone to time zone will be a breeze. If you will be connected to
a network, you should use UTC. Otherwise, Local Time is fine.
After choosing the format you want to store time in use the TAB key to
move the cursor down to the timezone window. Scroll through the
list (using 
and 
) until you find your
time zone and then press
