An os_time_and_date represents a single point in time with microsecond accuracy between 00:00:00.000000 Jan 1, 4713 b.c. and 23:59:59.999999 Dec 31, 32766 a.d., and can be constructed from one of the following.

The following example uses os_time_and_date to calculate the number of seconds a child named Drew has lived. The output of this example varies with time.
