Hi Folks,
because the Timezone information was obsolete, i recently updated the Java Timezone data from 'tzdata2003a' to 'tzdata2008g' by using 'tzupdater.jar'.
NSTimezone example for Asia/Shanghai:
System.out.println("***** Timezone = " + NSTimeZone.timeZoneWithName("Asia/Shanghai", true) + " / useDaylightTime = " + NSTimeZone.timeZoneWithName("Asia/Shanghai", true).useDaylightTime());
...returns...
***** Timezone = Asia/Shanghai (CST) offset 28800 / useDaylightTime = true
java.utils.TimeZone example for Asia/Shanghai:
System.out.println("***** Timezone = " + TimeZone.getTimeZone("Asia/Shanghai"));
...returns...
***** Timezone = sun.util.calendar.ZoneInfo[id="Asia/Shanghai",offset=28800000,dstSavings=0,useDaylight=false,transitions=19,lastRule=null]
Short: NTTimezone is telling me, that in Shanghai DST is used and java.util.TimeZone tells me that it is not used. I know that in Shanghai there is no DST at all.
Since NSTimezone inherits from java.util.TimeZone this difference is some kind of weird but i could not figure out how to update the NSTimezone information or anything else what would cause into correct results.
Any hints are welcome.
Regards
Andri
