Sun or Moon rise / set times appear to be wrong.
If you are attempting to reference current times, first make sure that your time controls are set to the present by tapping the Time Control button and then the refresh symbol.
At first glance, there may be occasions when the listed times for Sun or Moon rise / set may appear to be wrong. It's important to note, however, that all times listed within Sky Guide are future times. For example, if the Moon has already risen, the time shown for Moonrise is actually for the following 24-hour period — which could be different by over an hour. If you would like to know what time the Moon recently rose, you simply need to rewind the time using the Time Controls to something prior to the Moonrise. Then the listed times will update to reflect the change.
If that is not the issue, you may also need to check your location settings.
