Setup -> Time
Provides controls to set the time at which PSC computes its information, and options about how that time is changed and displayed. Tap X to dismiss the dialog without making any changes, or tap OK to install the new settings.
This section specifies the time to which PSC time is set when the dialog is closed.
This section sets how often and by what amount PSC automatically changes its time. The amount of change is called the Step interval. Time may be changed by one Step interval either manually each time the forward and backward toolbar buttons are tapped, automatically on a regular schedule, or both.
The toolbar buttons may also be used any time to manually step time in between automatic updates. When this setting is Off, then time is changed by the toolbar buttons only.
