A TimeStamp represents an instant in UTC as a number of 100-nanosecond ticks since midnight on 1 January 1601 UTC. The signed representation also permits instants before the epoch.

A TimeSpan represents a duration as a signed number of 100-nanosecond ticks. A negative value represents a duration in the opposite direction.
