Time Change Weirdness

[SINC]

Hey guys, this is an odd one... can someone explain this..

Normally in the time/alarm area...it allows you to choose between AM/PM.

For some strange reason.. it has broken it up into

A1/A2/A3/.../.../A11/A12
P1/P2/P3/.../.../P11/P12

Does anyone know what this is/means or how/why it has happened? I just did a new hard reset and have been slowly adding programs.. but this doesn't make sense.

Can i change it back without doing another hard reset?

Thanks. SINC
