I am testing Wakeup Time feature in power Management. However I found that system is not woekn up at exactly the time configured in wakeup time settings, but it is done at the offset if that time. For example: I cifnigured wakeup time to be 1:30 pm but pwrmgmt.log shows "system will now wake up at 2:25 pm". System actually wakes up at 2:35 pm. I want to know what crietria is used by machine to calculate wakeup time and what is the range of offset that can happen from configured wakeup time. (I have seen it upto 1 hour). Divya
