Java SimpleDateFormat Wrong Timezone after parsing
Why when i give input date string with GMT timezone, SimpleDateFormat parses it and outputs EET timezone?
public static String DATE_FORMAT="dd MMM yyyy hh:mm:ss z";
public static String CURRENT_DATE_STRING ="31 October 2011 11:19:56 GMT";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat(DATE_FORMAT, Locale.US);
simpleDateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
System.out.println(simpleDateFormat.parseObject(CURRENT_DATE_STRING));
And output is: Mon Oct 31 13:19:56 EET 2011 rather than Mon Oct 31 13:19:56 GMT 2011
You're printing out the result of Date.toString()
. A Date
doesn't have any concept of a timezone - it's just the number of milliseconds since the UTC Unix epoch. Date.toString()
always uses the system default time zone.
Note that you shouldn't be expecting "Mon Oct 31 13:19:56 GMT 2011" given that you've given a time which specifies a GMT hour of 11, not 13.
If you want to use a specific time zone for printing, you should use another DateFormat
for the printing, rather than using Date.toString()
. ( Date.toString()
keeps causing confusion like this; it's really unfortunate.)
