Andrew/Masayoshi After some research it appears that we have the openjdk-6-jre-lib package, version b11, installed and it is current according to Ubuntu. The latest openjdk-6-jre has the same version number. Masayoshi indicates in an earlier email that the current version is 6u17.
When I run the app I wrote (I've added a dump of the version info from system properties) that displays the offset for America/Chicago for 1900 I get: version=1.6.0_0 vendor=Sun Microsystems Inc. java.vm.specification.version=1.0 java.vm.specification.vendor=Sun Microsystems Inc. java.vm.version=1.6.0_0-b11 java.vm.vendor=Sun Microsystems Inc. timezone.id=America/Chicago date=Mon Jan 01 00:00:00 CDT 1900 1900/0:-18000000 1900/1:-18000000 1900/2:-18000000 1900/3:-18000000 1900/4:-18000000 1900/5:-18000000 1900/6:-18000000 1900/7:-18000000 1900/8:-18000000 1900/9:-18000000 1900/10:-21600000 1900/11:-21600000 The display is year/month#:offset. The same program running under the Sun jdk on windows gives me: version=1.6.0_07 vendor=Sun Microsystems Inc. java.vm.specification.version=1.0 java.vm.specification.vendor=Sun Microsystems Inc. java.vm.version=10.0-b23 java.vm.vendor=Sun Microsystems Inc. timezone.id=America/Chicago date=Mon Jan 01 00:00:00 CST 1900 1900/0:-21600000 1900/1:-21600000 1900/2:-21600000 1900/3:-21600000 1900/4:-21600000 1900/5:-21600000 1900/6:-21600000 1900/7:-21600000 1900/8:-21600000 1900/9:-21600000 1900/10:-21600000 1900/11:-21600000 Bill Bill Tims Renaissance Systems, Inc. 5426 Guadalupe, Suite 100 Austin, TX 78751 512-275-0344 -----Original Message----- From: gnu.andrew.ro...@gmail.com [mailto:gnu.andrew.ro...@gmail.com] On Behalf Of Andrew John Hughes Sent: Wednesday, December 02, 2009 8:54 AM To: Masayoshi Okutsu Cc: Bill Tims (RSI); i18n-dev@openjdk.java.net Subject: Re: <i18n dev> Open Jdk Timezone bug? 2009/12/1 Masayoshi Okutsu <masayoshi.oku...@sun.com>: > What is the time zone ID you are using? > > Thanks, > Masayoshi > > On 12/1/2009 1:55 AM, Bill Tims (RSI) wrote: >> >> From what I can find, this appears to be the right place to post >> this, if I'm wrong I would appreciate a pointer to the proper location. >> The database our app has to talk to has January 1,1900 12:00:00 am >> date in it.

If this is the system OpenJDK build, then it's an IcedTea build and thus includes a patch to use the system timezone data which is likely to be more up-to-date than that bundled with Sun's JDK. -- Andrew :-) Free Java Software Engineer Red Hat, Inc.
