When we use FogBugz to send email from within a case, the "Date" recorded is displayed with the server's time zone information. Since we're an on demand customer, it's "(GMT-05:00) Eastern Time (US & Canada)".
In our Regional settings we've chosen "(GMT+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna", yet it's not used as a source to display the date.
This can be confusing at times. Although the date is correctly written, I would expect it to be displayed with our time information.
