After reading the mktime man page, I take that back --- it's not
supposed to consider the passed-in values of the tm_wday and tm_yday
fields. The only documented reason for mktime to fail is if the
supplied values map to something outside the range of time_t,
which seems a tad unlikely. It'd be interesting perhaps to see
the raw header of your dump file, along the lines of
"od -c dumpfile | head".
