Whereas TimeSpan represents a summed amount of time between two given time values, the time portion of a Date object represents a single specific moment in time.

Minimum and Maximum Values

As for other value types, System.TimeSpan also provides two shared properties named MinValue and MaxValue that return respectively the following ticks: -10675199.02:48:05.4775808 ...
