DateTimeOffset Overcomes the drawback of DateTime. It expressed as a date and time of day, relative to Coordinated Universal Time (UTC).
For Example:
Given 4/18/2013 11:00:00 AM means absolutely nothing if you don't have a reference point. That could be 11:00:00 AM anywhere in the world. DateTimeOffset contains information about the timezone you are dealing with, which makes all the difference in THE WORLD!
