Generic Date representation
Combination of a Date and a TimeOfDay
Represents a point in time.
Represents a time of day. This is different from TimeSpan in that each component is represented within the limits of everyday time, rather than from the start of the Epoch. Effectively, the TimeOfDay epoch is the first second of each day.
This struct represents a length of time. The underlying representation is in units of 100ns. This allows the length of time to span to roughly +/- 10000 years.
