TimeZone.getTimeZone(“CST”) returns GMT

Question

I\'m converting time from CST to local time but getTimeZone doesn\'t seem to work properly.

    String cstTime = \"2013-06-21 14:00:00\";

    S         


        

Answer 1

One thing I found is that Java's TimeZone doesn't recognize "+09:00", but it does recognize "GMT+09:00" and "GMT+0900".

Answer 2

You can use "CST6CDT" Timezone it will automatically provide you the correct time when the Central Daylight Time (CDT) switched back to CST or vice versa.

Answer 3

From the javadoc for getTimeZone:

Returns a TimeZone corresponding to the given id, or GMT for unknown ids. 

An ID can be an Olson name of the form Area/Location, such as America/Los_Angeles. 
The getAvailableIDs() method returns the supported names. 

Try using getAvailableIDs?

Answer 4

The following code helped me.

TimeZone tzone = TimeZone.getTimeZone("Singapore");
// set time zone to default
tzone.setDefault(tzone);

Answer 5

The following seems to have worked for me as was facing similar issues:

Calendar c = Calendar.getInstance(TimeZone.getTimeZone("America/Chicago"));

Answer 6

for any date time conversion i would suggest using JODA date time, its help me solve a bunch of date time issues.

you can initialize a date with a time zone, and convert between them very easily

DateTimeZone zone = DateTimeZone.forID("Europe/London");

or

DateTimeZone zoneUTC = DateTimeZone.UTC;

from JODA DATE TIME API

DateTime(DateTimeZone zone)
Constructs an instance set to the current system millisecond time using ISOChronology in the specified time zone.
