How to Parse Date from GMT TimeZone to IST TimeZone and Vice Versa in android

by

Date does not have any time zone. It is just a holder of the number of milliseconds since January 1, 1970, 00:00:00 GMT. Take the same DateFormat that you used for parsing, set IST timezone and format your date as in the following example

    DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
    Date date = sdf.parse("2013-01-09T19:32:49.103+05:30"); 
    sdf.setTimeZone(TimeZone.getTimeZone("IST"));
    System.out.println(sdf.format(date));

output 

2013-01-09T19:32:49.103+05:30

Note that XXX pattern is used for ISO 8601 time zone (-08:00) since 1.7. If you are in 1.6 try Z. See SimpleDateFormat API for details of format patterns
