The DateTime property is not meant to be a
readable property. Instead, it is used to set the date and time in GMT
on the outgoing mail message.
Mailer.DateTime = "Fri, 02 May 1997 10:53:49 -0500"
will set the date and time in the mail headers of the outgoing email to
Friday, May 2, 1997 at 10:59:49 Eastern Time. The local time (GMT-0500)
will be translated to GMT .
