[threeten-dev] New time zone format patterns in LDML/CLDR

[yoshito_umaoka at us.ibm.com]

As I mentioned last week, CLDR TC had discussed about new time zone format 
patterns based on Java/JSR-310 proposal. In this morning, we had a 
discussion about the remaining item (time zone ID) and reached to a 
conclusion. Our conclusion is to use pattern "VV" for time zone ID, 
redefine already semantically deprecated "V" for CLDR short time zone ID 
(BCP 47 locale extension - time zone value) and new pattern "VVV" for time 
zone's exemplar location. In other words, we still want to reserve 'I' for 
future enhancement.

I updated the design document - 
http://sites.google.com/site/cldr/development/development-process/design-proposals/time-zone-offset-patterns
These new date format patterns should be included in UTR#35 LDML for CLDR 
23 release in March.

Of course, JSR-310 does not need to use the same definition, but if 
possible, it would be nice if JSR-310 can use the same definition 
(probably, just "VV" for now).

I think the distinction between 'X' and 'x' is practically more useful and 
I'd propose JSR-310 (and also, Java SimpleDateFormat)  to accept 'X' and 
'x' patterns as is.

Anyway, If you have any comments, please let me know. We might still make 
some minor adjustments if there are any strong objections from JSR-310 
community.

For Islamic calendar variants definitions - I'll post the proposal to CLDR 
TC soon, and it should be ready by the end of this month.

Thanks,
Yoshito
