ANSI 5.8.1 DateAndTime
This protocol describes the behavior that is common to date time objects. Date time objects represent individual points in Coordinated Universal Time (UTC) as represented in an implementation defined local time.
The exact properties of local times are unspecified. Local times may differ in their offset from UTC.
A given local time may have different offsets from UTC at different points in time.
All dates and times in the UTC local time are in the Gregorian calendar. Date times prior to the adoption of the Gregorian calendar are given in the retrospective astronomical Gregorian calendar.
The year 1 B.C. is astronomical Gregorian year 0. The year 2 B.C. is astronomical Gregorian year-1. The year 1 A.D. is astronomical Gregorian year 1. The offset of the UTC local time is zero.
ANSI 5.8.2 Duration
Represents a length of time.
ANSI 5.8.3 Duration factory
Represents protocol for creating a particular length of time.
ANSI 5.8.4 DateAndTime factory
Represents protocol for creating an abstraction for a particular day of the year.
