Log Message:
Update to 1.10. From the changelog:

- Some tests added in 1.09 would fail on a Perl without a 64-bit
  gmtime(). Reported by Jerome Eteve. RT #95345.

- A call to ->truncate( to => 'week' ) could fail but leave the object
  changed. RT #93347.

- The value of ->jd() is now calculated based on ->mjd() instead of the other
  way around. This reduces floating point errors a bit when calculating MJD,
  and should have a neglible impact on the accuracy of JD. Reported by Anye
  Li. RT #92972. See the ticket for a more detailed description of what this
  fixes.

- Attempting to construct a DateTime object with a year >= 5000 and a time
  zone other than floating or DST now issues a warning. This warning may go
  away once DateTime::TimeZone is made much faster. Inspired by a bug report
  from Lloyd Fournier. RT #92655.
