I use the alarm clock function of the built-in clock app, and usually it works great. Occasionally, however, the clock app gets off one hour relative to the system clock. Notably, the system clock always seems to be right -- I don't ever see it off by the hour, so it isn't clear to me from where the clock App gets the wrong time. I suspect this is somehow related to the fact that I live near the boundary between eastern and central time, and sometimes the problem does occur when I travel between the two. Other times, however, it happens when I haven't been traveling at all. It's really a bummer because I don't regularly check the time on the clock app (although, clearly I should!), but I use a daily alarm, so some days it just doesn't go off. I haven't been able to identify a specific trigger for the error. Anyone know of a fix, other than power-cycling the phone? Or, are there other clock apps that keep a better connection to the system clock?
