Update to 20140314-build-5.0-008

GF-62151,GF-62138: The date formatter now calculates offsets properly
between time zones that differ by fractions of an hour. For example,
St. John's, Canada has an offset from UTC of -2:30, or Kathmandu, Nepal
which has an offset of 5:45 from UTC. Added unit tests to verify the fix.
