When you do Tablicious time zone related stuff on a Linux box that's missing tzdb or has it installed somewhere besides /usr/share/zoneinfo, it raises an error about an invalid zoneid. Like this:
>>>>> processing /usr/share/octave/packages/tablicious-0.4.2/@datetime/datetime.m
***** test datetime ('2011-03-07 12:34:56', 'TimeZone', 'America/New_York');
!!!!! test failed
Undefined TimeZone: America/New_York
Would be nice to have the error say "missing tzdb package" instead; it took us a while to figure out what was going on here. Maybe even fall back to the bundled tzdb, but think about that for a bit first.
TODO
[ ] Better error handling for missing tzdb.
[ ] Dynamic tzdb detect, which detects the whole db being missing, instead of treating it as a single missing zone file indicating an invalid zone id; details in error message.
[ ] Figure out how to build a tzdata-less Ubuntu VM or container for testing this.
[ ] Caching of parsed time zone files and tab, while we're in here.
