tzname CST identified but not understood. Pass `tzinfos` argument in order to correctly return a timezone-aware datetime

[reagle]

How do you specify a time zone? When specified in quick, they don't stick, and in add I get an error.

If you use TZ names from the tzdatabase, then you don't get the error (however, I can repro the non-stickiness).

Regarding "CST" vs the tzinfo db names, it's handy that the library is telling us what to do to make it better, however. I wonder if that would help the stickiness too.
