How about adding a version file in the tzdata database, say _tz_version.txt,
that contains something like:
::::::::::
_tz_version.txt
::::::::::
tzdata 2003a
_tz_version.txt could be a text file that is part of the tzdata source
tar file. zic could install it to the /usr/lib/zoneinfo/ (or wherever)
directory.
Then zdump -V (new option) could read the _tz_version.txt file, and
print the version as "2003a".
An inconsistency is that the files in the /usr/lib/zoneinfo/ directory
are zoneinfo files, while _tz_version.txt is not. A user (or
script) could try to set TZ=_tz_version.txt even though it is not a
valid zoneinfo file. It could help to create a new src directory under
zoneinfo, that would contain source files.
