How can I get daylight saving time rule?

[David Chen]

Hi, there:

In JDK, is there any straightforward way to get daylight saving time rule for a particular timezone, like start(end) date, start(end) time? Yes, as someone said, I can print out timezone (ex. System.out.println(myTimeZone)) like:
java.util.SimpleTimeZone[id=America/Los_Angeles,offset=-28800000,dst
Savings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=3,startDay=1, ..............]
My question is: besides besides parsing above timezone output string, is there any other method in JDK I can use to get those information? Highly appreciated if anyone can give me any suggestion.


Thanks a lot in advance

David

To answer the question that was actually asked - no, I don't think there is. The API doesn't seem to provide any way to get the info you want. As far as parsing is concerned - to make this easier (a little, maybe) you might try using XStream to write an XML representation of each instance. Might be a little easier to read & parse. Still not what you wanted, I imagine, but I don't see a better alternative.
