Unix.mktime is documented as taking a tm struct. However, this tm
struct uses a bool for tm_isdst. mktime itself will accept three
values for this field (1, 0, or -1 for yes, no, and figure-it-out).
I believe this functionality is important because I typically don't
know whether dst is in effect when parsing a date, so I rely on
mktime to just do the right thing.

Actually, Unix.mktime ignores the tm_isdst boolean field of its
argument, and calls mktime() with dst = -1. So, you get the behavior
you expect. Perhaps the documentation should mention this.
