Time-related data types

A Timespan defines the length of a duration of time, and a Timestamp defines a point in time. For example, “two hours” is a duration that can be represented as a Timespan, while “three o'clock in the afternoon UTC on 8 November, 2018” is a point in time that can be represented as a Timestamp. Both types can use nanosecond values if it is available on the platform.
