well its all pretty simple as long as you have the reg edit....it was bothering me and no one posted on how to change it or i just couldnt find it.....so i figured out myself...so instruction time....of course link first

1. open reg edit of course...and if you dont have it its above
2. open folder hkey current user
3. open folder software
4. open folder A_C
5. open slide2unlock
6. go to time format and tap it
7. then just change the 'H' to an 'h'
now this only works if you have the a_c slide2unlock im guessing because i dont know if there is another slide2unlock
but there you go
