I have three Sansa Clip+. Their date and time is accurate despite being off for long periods of time. Does the clock use its own battery such as a clock battery? Or does the clock use phantom power from the main battery?
It does not make sense for the MP3 player to have a clock in which users have to go to settings > system settings > date and time to see the date and time. Is the date and time used for some other purpose?
