I have an alarm for Monday-Thursday at 6 a.m., and as far as I can tell (I'm not 100%), it works fine. But I just created a new alarm for Friday and Saturday, also at 6 a.m., and this morning, it did not go off at 6 on the dot, but at 6:09. Then, after using snooze a few times, it didn't go off again at the right interval. I'm a little mad because this almost messed up my agenda for the morning. Is this even possible or am I imagining things? If so, why would it be weird like this?
