Thank you all.
1. When I have actived the schedule, there is same problem.( AM automatic chenged to PM).
actually, at task scheduler of windows, the schedule have set to 9:30PM.
2. When I have chenged time at PM to PM, the value of time has chenged. the PM is still PM.
screen shot:
active schedule: ( I set it 9:30 AM)
task scheduler:
changed Time at PM ( from 9:30 PM to 9:10PM)
