Differnce between time.

[Neeba Rebbaca]

I want to find the differnce between two time which is in 12 hrs format.

String fromtime = 12.00.00 AM
String toTime   = 9.00.00 AM

SimpleDateFormat sdf_time = new SimpleDateFormat("HH:mm:ss a");
Date frm_time = sdf_time.parse(fromtime);
Date to_time = sdf_time.parse(toTime);

Calendar fromtime_calendar = Calendar.getInstance();
Calendar totime_calendar = Calendar.getInstance();

fromtime_calendar.setTime(frm_time);
totime_calendar.setTime(to_time);


long milis1 = fromtime_calendar.getTimeInMillis();
long milis2 = totime_calendar.getTimeInMillis();

long diff = milis2 - milis1; 
long diffHours = diff / (60 * 60 * 1000); //since i want the time differnce in hours

But instead of getting 9 hrs differnce, i'm getting only 3 hrs differnce.

Where i'm going wrong?

Check on the letter for Hour.

Just for the sake of providing docs that aren't really old:

And please post actual code--those dates aren't even parseable by your own code.
