If you use AlarmManager with an RTC alarm, the alarm will adjust for changes to the system time. The possible exception would be if the time change skips over the time of the alarm -- I have not tried that.

For reboots, you will need to reschedule your alarms. This is typically accomplished via a BOOT_COMPLETED BroadcastReceiver.
