DateZone: get timezone series from TZDIR
The DateZone plugin calls `getTimeZoneSeriesFromOlsonFile` using the hard-coded path /usr/share/zoneinfo. While that may work just fine on most Linux distros, it does not work on NixOS since that directory is always locates somewhere under /nix/store. Based on mild research, it seems the environment variable TZDIR is commonly set to the absolute path to `zoneinfo` (but without a trailing slash). This change modifies the DateZone plugin to first try getting the zoneinfo path from the TZDIR environment variable, falling back to the hard-coded path /usr/share/zoneinfo
