Problem with time difference

Question

I should calculate the difference between two times.and store it in database..
My code is:
long ms = (from.getTime() - to.getTime());
java.sql.Time nohrs = new java.sql.Time(ms);Suppose let from = 12:20:36
to=12:20:26
I should get 00:00:10 but what I am getting is 5:30:10
I think its taking GMT time,how to avoid this

Answer 1

Hope I am not too late in answering this !
The problem is new java.sql.Time(ms) will calculate the TIME WITH CORRESPONDS TO milliseconds since January 1, 1970, 00:00:00 GMT, so in your example it is
new java.sql.Time(10000) ie January 1, 1970, 00:00:10 GMT and it will converted to your time zone. ie January 1, 1970, 05:30:10 .
this can be adjusted / solved by subtracting the milliseconds correcponds to your time zone , using .getTimezoneOffset().
here is the piece of code i used, use after proper checking if needed
public class testTime { public static void main(String arguments[]) throws Exception {
Date from = new Date(2005 , 7 , 19 , 12 ,20 , 36);
Date to = new Date(2005 , 7 , 19 , 12 ,20 , 26);
long ms = (from.getTime() - to.getTime());
long msNew = (from.getTime() - to.getTime() + (new Date().getTimezoneOffset() * 60 * 1000 ));
java.sql.Time nohrs = new java.sql.Time( ms );
java.sql.Time nohrsNew = new java.sql.Time( msNew );
System.out.println(nohrs);
System.out.println(nohrsNew);}}
========my result ===============

01:00:10
00:00:10
