JTZU searches your system for IBM SDKs and JREs and updates each one found.
The tool works in two modes: You can use JTZU to update individual Java instances or multiple instances on local or network drives.
Update your time zone from the Settings section of your Hootsuite dashboard.
If your dashboard is displaying a time or date different from your selected time zone, the time zone settings on your computer or mobile device may require updating.
JTZU updates the time zone information in IBM-supplied releases and service refreshes of the Java™ SDK and JRE.
With this tool, you can adopt changes to DST when you are unable to apply a service refresh, or when a service refresh is not yet available that incorporates the time zone changes you need.
Back to top To see which time zone updates are included for different versions of JTZU, see Olson time zone updates for Java JRE and SDK service refreshes for IBM products Warning Applying IBM product maintenance that contains earlier time zone data will remove the updates applied by this tool.
You must rerun this tool to restore the time zone data to the latest level.
The JVMs from IBM tolerate but do not utilize leap seconds, so they do not need updating with timezone data which has leap second information to work correctly.
