bin/date vary.c
Log:
Always give mktime a timeval with tm_isdst set to -1, otherwise
things get a bit out-of-phase when we step backwards 1 hour from
between 0:00 and 1:00 on the first of the month following the
transition into Summer time. This is probably actually a bug
in mktime().
PR: 10963
If mktime() fails and 68 < year < 138, assume that the reason is
because of Summer time and adjust up or down according to our
adjusting context by one hour. This assumes that all DSTs are
multiples of 1 hour.
