I'm continuously changing the minutes of my C5.
It seems like the minutes or seconds go by faster than the coordinated time available on internet.
E.g: I set two alarms at 21:00. In my C5 and in a Casio watch. Both alarms sounded at the same time.A month later my C5 alarm sounded 5 minutes before the Casio watch. (And yes, The Casio watch still has the same time as the one set on my computer)
Anyone else having this problem?
