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.
