The tests enabled by "-utzdata" check UTC to local and back conversions at several points around *every* time transition in *every* timezone. On systems with a complete installation of IANA tzdata, this is a lot of test points.

These tests were supposed to be exhaustive and I did not expect them to be run by default.  that's why I introduced the -utzdata flag in the first place.
