Are you using original atd or atd-over-fso? atd-over-fso has the
following bug (which I have not fixed and it may be related): if you set
an alarm at time t0 and t0 happens to be the next alarm and then you
remove alarm t0 and a later alarm will become the next alarm
atd-over-fso will nevertheless wake up the phone at time t0.
