Subject [jira] Commented: (HARMONY-493) daylight savings parsing problem
Date Mon, 07 Aug 2006 11:28:16 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-493?page=comments#action_12426200 ] 
            
Alexey Petrenko commented on HARMONY-493:
-----------------------------------------

I've modified testcase a little:

import java.util.TimeZone; 
import java.util.Calendar;
import java.util.Date; 

public class Jira493aTest { 

    public static void main(String[] args) {         
        TimeZone zone = TimeZone.getTimeZone("Europe/London"); 
        Calendar cl = Calendar.getInstance(zone);
        System.err.println("Calendar class: "+cl.getClass().getName());
//      d = df.parse("March 26, 2006 01:50:00.000"); 
        cl.set(2006, 02, 26, 01, 50, 00);
        cl.set(Calendar.MILLISECOND, 0);
        System.err.println("Time: " + cl.getTimeInMillis());
        System.err.println("In daylight saving?: " + zone.inDaylightTime(cl.getTime()));
    } 
} 

Here is a result from RI:
Calendar class: java.util.GregorianCalendar
Time: 1143337800000
In daylight saving?: true

Here is a result from Harmony:
java version "1.5.0"
pre-alpha : not complete or compatible
svn = r429290, (Aug  7 2006), Windows/ia32/msvc 1310, debug build
http://incubator.apache.org/harmony
Calendar class: java.util.GregorianCalendar
Time: 1143334200000
In daylight saving?: false

So the bug is not in SimpleDateFormat but in TimeZone and probably GregorianCalendar classes.
