Proposal: Contribution of a TimeZone Updater Tool ?

[Baesken, Matthias]

Hello Andrew ,  I think such a tool would be a great contribution .

I hear often customers ask about timezone updates , and  such a tool would give them the ability to update 
  to the  latest IANA data (instead of waiting for an OpenJDK  release  with new timezone data ). 

Best regards, Matthias

> Support rearguard JDK tzdb.dat standard format for JDK8,11,13+, both
> Hotspot and OpenJ9
> Provided build script downloads the latest(or specified) IANA data and
> builds the packaged tool with rearguard format.
> The built standard-alone updater tool has multiple modes of operation:
> Using an interactive GUI:
> Select to update a specific JDK home
> Scan and update all JDKs found
> From command line, Interactively or Silent/Automated:
> Scan and update all JDKs found
> Scan and update all JDKs based on a selective search configuration
> Scan and discover what JDKs need updating (no update performed)
> Scan and update specific JDK locations
> 
> Future expansion would be the addition of vanguard support.
