Need TimeZone data

[Manish Ramrakhiani]

Hello All,

I need the timezone details of all possible time zones, I need following things.
- TImezone name
- Offset with respect to GMT
- does it support day light saving
- Offset considering if it supports day light savings

I basically need all this informtion and have to create a table in database, i check out Timezone API in jdk
but does not seem to be of help.

Any pointers how do i get it?

Thanks,
Manish Ramrakhiani

Googled it and the first entry gave me this.

http://www.exampledepot.com/egs/java.util/GetAllZones.html

 
Date today = new Date();

// Get all time zone ids
String[] zoneIds = TimeZone.getAvailableIDs();

// View every time zone
for (int i=0; i<zoneIds.length; i++) {
    // Get time zone by time zone id
    TimeZone tz = TimeZone.getTimeZone(zoneIds[i]);

    // Get the display name
    String shortName = tz.getDisplayName(tz.inDaylightTime(today), TimeZone.SHORT);
    String longName = tz.getDisplayName(tz.inDaylightTime(today), TimeZone.LONG);

    // Get the number of hours from GMT
    int rawOffset = tz.getRawOffset();
    int hour = rawOffset / (60*60*1000);
    int min = Math.abs(rawOffset / (60*1000)) % 60;

    // Does the time zone have a daylight savings time period?
    boolean hasDST = tz.useDaylightTime();

    // Is the time zone currently in a daylight savings time?
    boolean inDST = tz.inDaylightTime(today);
}

Check it out. Hope it's what you want.

Thanks Sridhar.

Actually I was searching it If it was possible to get directly through SQL, hence did not pay much attention to get it from java.
However I still need one more detail.

If timezone supports day light saving then what will be the offset while it is enabled?

Thanks again.

How do I get this detail:

Read this: EaseUp. Really, if it's urgent then instead of waiting for an answer here you could look it up in the API documentation. For which the link is here: TimeZone.

Dude, EaseUp

Have you looked at the Java API docs for TimeZone? Does it have any method which will return the offset for a particular date? Does it take into account the DST?
Please ShowSomeEffort

PS. Darn. Paul beat me to it while I was searching for those links.
