Proposal: Contribution of a TimeZone Updater Tool ?

[Andrew Leonard]

Hi,
I would like to gather interest/comments on whether it would be of 
interest or appropriate for the contribution of a JDK TimeZone Updater 
Tool to the community?
Here at IBM we have a timezone updater tool which we have extended to work 
with OpenJDK JDK's (jdk8 and above), and would like to contribute to 
either OpenJDK, or if not suitable then to AdoptOpenJDK. It make sense to 
offer upstream first, so would like to get feedback on the idea please? A 
quick summary of the features are:

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.

Comments welcome?

Thanks
Andrew
