Mail: Get message date using INTERNALDATE

Browse source 
Parsing mail headers and its date format is a rather tedious task,
especially if you want to support the obsolete syntax, so let's ask the
server to do it for us!

This will convert the date to our local time and display it in a
sortable and fixed-width format "%Y-%m-%d %H:%M:%S".
