Hi,

that's because you told GNU Emacs to do so :-)

There are two ways of setting the delay:

`midnight-delay-set' accepts a number as second arg, specifying the number of
seconds after the midnight when the midnight-timer is run.  So
(midnight-delay-set 'midnight-delay 2400) would have done the trick. 

You chose to use the other way by passing a string, which is then passed as the
first argument to `run-at-time'.  But for `run-at-time', if the time is
specified using a string, it is taken to be a time _today_, even if already in
the past.  So I bet you fired up Emacs after 0:40am and then midnight runs
immediately.

You can read about this in the GNU Emacs Lisp manual, see "Timers".

Hope this helps,

Toto
