67 No kidding the offset is large. If you just sent this email a few
68 minutes ago. The email's send date is "Tue, 10 Jan 2012 07:33:49 -0500".
69 The mail server which received it logged it as on "Tue, 10 Jan 2012
70 10:33:53 -0700", which suggests you're about five hours off.

72 Hm. That sounds like your tz (-0500) is being applied twice.
