[issue1652] Conversion from Bazaar shifts timestamps to UTC

[Greg Ward]

New submission from Greg Ward <greg-hg at gerg.ca>:

I'm using "hg convert" to convert a Bazaar branch.  The latest revision in
Bazaar looks like

revno: 211
committer: Greg Ward <greg at gerg.ca>
branch nick: pyfastimport
timestamp: Tue 2009-05-05 11:27:15 -0400

After conversion to Mercurial, the timestamp has been shifted to UTC:
