It's very easy.  Simply go to Europe where the entire population uses
24-hour time and it will switch by itself. ;-)

Seriously, 24-hour time is better.

Ok, if you insist...you have to remove and disassemble the clock to
get to the back of the circuit board.  Use a sharp tool (not a #11
blade, the end is too fragile) to cut the trace between the two pads
marked 24, and make a solder bridge or solder a wire across the pair
marked 12.  It's not hard but you have to be reasonably careful with
all parts of the job.

There may be zero, one or two bits of loose polarizing film in the
LCD assembly.  If so, they have to be lined up correctly when
reassembling.  You must be able to see through both at once.  If you
get it backwards you'll end up with a black screen with clear numbers
instead of the other way around.
