this is basically a copy of the bug i filed for slimserver months ago.  but this
is really crappy behavior.

couple of examples:

- when your time is 12h and the hour is a single digit, when you go in to set
alarm time it starts on the 2nd digit, so you have to press left to enter a 1
for 10+hrs

- when you enter a digit and let it sit there for a sec, the text entry skips
the next digit and you have to go back (like you enter 1 for 1:00, the cursor
skips to the second 0)

- entering 1 while on the am/pm field goes for PM, 2 goes for AM...  seems like
it should be the other way around
