Currently, the Firebird 4 snapshots still include TZ database 2018e. The
latest version at this time is 2019b (2019-07-01), although ICU doesn't
seem to have added it yet on
https://github.com/unicode-org/icu-data/tree/master/tzdata/icunew.
What is the plan to keep this up-to-date for releases?
Another thing I was wondering about, if I update manually, is there a
default location that will work for the `res` files? The instruction
says "The easiest way to update is downloading the *.res files in a
directory and set ICU_TIMEZONE_FILES_DIR environment variable pointing
to it.", but that isn't always an option when running Firebird as a
service on Windows.
I tried putting them in the root Firebird folder, but that doesn't work
without setting the environment variable. And integrating them into
icudt63l.dat requires access to the icupkg tool which doesn't seem to be
readily available except through building it yourself, which isn't a
common action on Windows.
