I have been searching over the net from past few hours to get the datetime in my system timezone.
When I use calendar.getTimezone.getDefaultName()
it always returns me GMT
. Ideally it should return my current timezone, which is IST
.
I am trying to convert this string "2014-02-14T06:04:00:00", which is in GMT
to my timezone datetime. It always returns me the same time in GMT
.
All I see is that everyone is suggesting to use Timezone
, i.e,
dateFormatter.setTimezone("any_arbitary_timezone");
Point is my application will be used in different geographical locations. I cannot set it to a particular timezone. It should be set to the system timezone, so that it can display in whichever timezone the user is currently in.
Here is a way to get the id of a TimeZone
that matches your local system clock's offset,
Calendar cal = Calendar.getInstance();
long milliDiff = cal.get(Calendar.ZONE_OFFSET);
// Got local offset, now loop through available timezone id(s).
String [] ids = TimeZone.getAvailableIDs();
String name = null;
for (String id : ids) {
TimeZone tz = TimeZone.getTimeZone(id);
if (tz.getRawOffset() == milliDiff) {
// Found a match.
name = id;
break;
}
}
System.out.println(name);
