Is icu4c/source/data/zone/tzdbNames.txt obsolete?

[Victor Chang]

Hi,

We followed this ICU documentation to update the time zone data in the ICU.

https://unicode-org.github.io/icu/userguide/datetime/timezone/#updating-the-time-zone-data

Essentially, the following 4 files need to be updated.

• zoneinfo64.res
• windowsZones.res
• timezoneTypes.res
• metaZones.res

However, we found this tzdbNames.res in the binary ICU packaged data. Is it used by ICU? The source of tzdbNames can be found here.

https://github.com/unicode-org/icu/blob/maint/maint-76/icu4c/source/data/zone/tzdbNames.txt

The last update was 7 years ago. I guess that this file is obsolete? Or will the file get updated in the future ICU release?
