There are three ways to
change the time the sky map or compass info is calculated
for:
- The "Now"
button
 .
If the now button is active (white clock on dark
background) Planetarium uses the current time
from the Palm clock and updates the display every
minute.
- Set the date or time
manually. Choose the menu items Options/Set Date
and Options/Set Time or just tap on the date and
time text at the lower left to open the date and
time entry screens. You can set the date and time
to any value in the range of the Palm calendar
(years 1904 to 2031).
 Use the Page up/down scroll
buttons. Each press of these buttons adds or
subtracts a given value to the current time. This
way you can step through the time and observe the
sky interactively. Use the menu 'Time Increment'
to select the appropriate time step. The odd
numbers are multiples of 23h56m (one sidereal
day) and are useful for studying planetary
motions in Sky view because the stars stay at
their positions after each step.
