Tom, it's a directory format dump, what file would make the most sense to run oc on? Or does this not work w/a directory?

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".
