Remarks

Implements a time span.

A time span is the difference between two dates and times. For example, the time span between 12:00:00 January 1, 2000 and 18:00:00 January 2, 2000 is 30.0 hours. Time spans are measured in positive or negative ticks depending on whether the difference is measured forward or backward. Each tick has a resolution of 0.1 microseconds (= 100 nanoseconds).

In conjunction with the companion class FDateTime, time spans can be used to perform date and time based arithmetic, such as calculating the difference between two dates or adding a certain amount of time to a given date.

When initializing time span values from single components, consider using the FromHours, FromMinutes, FromSeconds, Zero, MinValue and related methods instead of calling the overloaded constructors as they will make your code easier to read and understand.
