Parse DATE-TIME-STRING, and return (values UNIVERSAL-TIME FRACTION).
DATE-TIME-STRING must represent the date-time after 1900-01-01T00:00:00Z.
Parsable Formats:
* RFC822 Genus: RFC822 (RFC1123, RFC2822, RFC5322), RFC850 (RFC1036) and asctime.
* ISO8601 Genus: ISO 8601 (:1988, :2000 and :2004. except for no-year format),
W3CDTF, RFC3339.
* Broken format: The above formats with little broken.
Examples:
* (parse-date-time "Thu, 23 Jul 2013 19:42:23 JST")
=> 3583564943, 0
* (parse-date-time "2013-07-23T19:42:23+09:00")
=> 3583564943, 0
* (parse-date-time "23 Jul 13 19:42:23 +0900")
=> 3583564943, 0
* (parse-date-time "Thu Jul 23 19:42:23 JST 2013")
=> 3583564943, 0
* (parse-date-time "2013-07-23T19:42:23.45Z")
=> 3583597343, 0.45

Return offset for the time-zone-abbrev. If not find offset, return NIL.
Return T if YEAR is a leap year, otherwise NIL. c.f. RFC3339, (Appendix C. Leap Years)
Parse DATE-TIME-STRING with ISO8601, W3CDTF or RFC3339 format,
and return (values UNIVERSAL-TIME FRACTION).
