Question

hello
I have been trying to calculate the duration between t0 and now .I have tried everything
but I'm having one hour more .
here is the last test I have done
SimpleDateFormat df=new SimpleDateFormat("hh:mm:ss");
String arriving;
String now;
Date d1,d2;
      try
         arriving="10:15:20";
         now="10:30:20";
         d1 = df.parse(arriving);
          d2=df.parse(now);
      } catch (ParseException ex)
         ex.printStackTrace();
Date dd = new Date(d2.getTime() -d1.getTime());
System.out.println("duration   dd   is "+ dd);here is the result i get
Thu Jan 01 *01*:15:00 CET 1970

Date dd = new Date(d2.getTime() -d1.getTime() --(3600000 ));
This will only work for computers in your time zone, since you are hardcoding the offset.
Instead, I encourage you to use the same time zone for all of your computations so you don't have to deal with it.
You should be able to pass the time zone as an argument to the date strings that are being parsed.
Edit: warnerja beat me to it.
