The time zone information used by Java is taken from the Olson timezone database.
The time zone updates are applied by updating your Java SDK or JRE or running the
IBM Time Zone Update Utility for Java (JTZU).
For general information about updating Java SDKs with new DST information,
see
Guidance on updating Java SDKs and JREs for Daylight Saving Time (DST) changes.
Please note: IBM accepts no responsibility for the accuracy or completeness
of the information obtained from the Olson database: it is provided for guidance only and
should not be regarded as definitive.
