- class date
- An idealized naive date, assuming the current Gregorian calendar always was, and always
will be, in effect. Attributes: year, month,
and day.
- class time
- An idealized time, independent of any particular day, assuming that every day has
exactly 24*60*60 seconds (there is no notion of "leap seconds" here).
Attributes: hour, minute, second, microsecond, and tzinfo.
- class datetime
- A combination of a date and a time. Attributes: year, month, day, hour, minute, second, microsecond,
and tzinfo.
- class timedelta
- A duration expressing the difference between two date, time, or datetime instances to microsecond
resolution.
- class tzinfo
- An abstract base class for time zone information objects. These are used by the datetime and time classes to provide a
customizable notion of time adjustment (for example, to account for time zone and/or
daylight saving time).
Objects of these types are immutable.
Objects of the date type are always naive.
An object d of type time or datetime
may be naive or aware. d is aware if d.tzinfo is not None
and d.tzinfo.utcoffset(d) does not return None.
If d.tzinfo is None, or if d.tzinfo
is not None but d.tzinfo.utcoffset(d) returns None,
d is naive.
The distinction between naive and aware doesn't apply to timedelta objects.
