Parse dates in a hopefully more portable fashion

On GNU, struct tm doesn't have tm_gmtoff and %z or %Z in strptime
do nothing. mktime(3) interprets the struct as local time, regardless
of any tm_gmtoff, except on FreeBSD. Parse the zone portion of the
date manually, subtract it from the struct tm fields, and call
timegm(3). While here, correctly parse the optional seconds portion
of the time.
