On Groovy using python3-icu to verify the same change but for the bundled icu-data:
bdmurray@clean-groovy-amd64:~$ python3 -c "from datetime import datetime; from icu import ICUtzinfo, TimeZone; tz = ICUtzinfo(TimeZone.createTimeZone('Pacific/Fiji')); print(str(tz.utcoffset(datetime(2020, 11, 10))))" 13:00:00 bdmurray@clean-groovy-amd64:~$ sudo apt-get install tzdata Reading package lists...

Additionally, upstream removed the "old" SystemV timezones, but the SRU will ensure that they are kept. Subsequently, these should be checked for using the following: zdump -v SystemV/MST7 zdump -v America/Phoenix The information returned by SystemV/MST7 should be included in America/Phoenix's output. Verification is done with 'zdump'. The first timezone that gets changed in the updated package is dumped with "zdump -v $region/$timezone_that_changed" (this needed to be greped for in /usr/share/zoneinfo/). [For example: "zdump -v Africa/Casablanca".] This is compared to the same output after the updated package got installed. If those are different the verification is considered done.
