Hi Venkat,

  I think what you are lookng for is the DST_OFFSET value for a given Calendar set to the TimeZone in which you are interested.

Java doc snippet says...

DST_OFFSET
public static final int DST_OFFSET 

Field number for get and set indicating the daylight savings offset in milliseconds. 
This field reflects the correct daylight saving offset value of the time zone of this Calendar if the TimeZone implementation subclass supports historical Daylight Saving Time schedule changes

  Hope this helps,

  Regards,

  Dharmendra

ps: have a good day!

Yes, I have used them. What I want is the dates and not the duration of
fwd/bwd switch.

Regards,
Venkat.

Have you checked super class methods for SimpleTimeZone,

  For example, TimeZone.getTimeZone("GMT-8").getID() returns
"GMT-08:00".
and also method
getDSTSavings()
