[top] / zope / interface / common / idatetime / IDateTimeClass
This is the datetime class interface.
min
(Attribute)
The earliest representable datetime
max
(Attribute)
The latest representable datetime
resolution
(Attribute)
The smallest possible difference between non-equal datetime objects
* = required
fromordinal(ordinal)
Return the datetime from the proleptic Gregorian ordinal.
January 1 of year 1 has ordinal 1. ValueError is raised unless 1 <= ordinal <= datetime.max.toordinal(). The hour, minute, second and microsecond of the result are all 0, and tzinfo is None.
fromtimestamp(timestamp, tz=None)
Return the local date and time corresponding to the POSIX timestamp.
Same as is returned by time.time(). If optional argument tz is None or not specified, the timestamp is converted to the platform's local date and time, and the returned datetime object is naive.
Else tz must be an instance of a class tzinfo subclass, and the timestamp is converted to tz's time zone. In this case the result is equivalent to tz.fromutc(datetime.utcfromtimestamp(timestamp).replace(tzinfo=tz)).
fromtimestamp() may raise ValueError, if the timestamp is out of the range of values supported by the platform C localtime() or gmtime() functions. It's common for this to be restricted to years in 1970 through 2038. Note that on non-POSIX systems that include leap seconds in their notion of a timestamp, leap seconds are ignored by fromtimestamp(), and then it's possible to have two timestamps differing by a second that yield identical datetime objects.
See also utcfromtimestamp().
utcfromtimestamp(timestamp)
Return the UTC datetime from the POSIX timestamp with tzinfo None.
This may raise ValueError, if the timestamp is out of the range of values supported by the platform C gmtime() function. It's common for this to be restricted to years in 1970 through 2038.
See also fromtimestamp().
utcnow()
Return the current UTC date and time, with tzinfo None.
This is like now(), but returns the current UTC date and time, as a naive datetime object.
See also now().
combine(date, time)
Return a new datetime object.
Its date members are equal to the given date object's, and whose time and tzinfo members are equal to the given time object's. For any datetime object d, d == datetime.combine(d.date(), d.timetz()). If date is a datetime object, its time and tzinfo members are ignored.
now(tz=None)
Return the current local date and time.
If optional argument tz is None or not specified, this is like today(), but, if possible, supplies more precision than can be gotten from going through a time.time() timestamp (for example, this may be possible on platforms supplying the C gettimeofday() function).
Else tz must be an instance of a class tzinfo subclass, and the current date and time are converted to tz's time zone. In this case the result is equivalent to tz.fromutc(datetime.utcnow().replace(tzinfo=tz)).
See also today(), utcnow().
today()
Return the current local datetime, with tzinfo None.
This is equivalent to datetime.fromtimestamp(time.time()). See also now(), fromtimestamp().
