Detailed Description

Represents an instant in time, typically expressed as a date and time of day.

Remarks

Time values are measured in 100-nanosecond units called ticks, and a particular date is the number of ticks since 12:00 midnight, January 1, 0001 A.D. (C.E.) in the Gregorian Calendar (excluding ticks that would be added by leap seconds).
There is no time zone information associated. You need to keep track of the used time zone separately. That can be done by keeping an additional TimeSpan around which represents the delta to GMT or by simply using GMT everywhere in the program.
When constructing an instance via DateTime::fromTimeStamp(), DateTime::fromChronoTimePoint() or DateTime::fromIsoStringLocal() the time zone deltas are "baked into" the DateTime instance. For instance, the expression (DateTime::now() - DateTime::gmtNow()) returns one hour in Germany during winter time (and not zero although both instances represent the current time).

Todo

Allow to determine the date part for each component at once to prevent multiple invocations of getDatePart().
