Can anyone recommend a way to determine the timezone that an email was sent from in C#?
Looking at the header information of an email includes information like:
Received: from mail-ew0-f211.google.com (123.85.219.211) by UKExchange
(10.1.10.99) with Microsoft SMTP Server id 1.2.345.6; Tue, 13 Apr 2010

There are a number of "Received: from" and "Received: by" keys with a date, time and timezone indicated on the end.
Which one of these should I attempt to parse?
Is this a reliable way to figure out the sender's timezone, or anyone recommend a better way?
