Time handling.

class iris.time.PartialDateTime(year=None, month=None, day=None, hour=None, minute=None, second=None, microsecond=None)[source]#

Bases: object

A PartialDateTime object specifies values for some subset of the calendar/time fields (year, month, hour, etc.) for comparing with datetime.datetime-like instances.

Comparisons are defined against any other class with all of the attributes: year, month, day, hour, minute, and second. Notably, this includes datetime.datetime and cftime.datetime. Comparison also extends to the microsecond attribute for classes, such as datetime.datetime, which define it.

A PartialDateTime object is not limited to any particular calendar, so no restriction is placed on the range of values allowed in its component fields. Thus, it is perfectly legitimate to create an instance as: PartialDateTime(month=2, day=30).

Allows partial comparisons against datetime-like objects.

Args:

year (int):
month (int):
day (int):
hour (int):
minute (int):
second (int):
microsecond (int):

For example, to select any days of the year after the 3rd of April:

>>> from iris.time import PartialDateTime
>>> import datetime
>>> pdt = PartialDateTime(month=4, day=3)
>>> datetime.datetime(2014, 4, 1) > pdt
False
>>> datetime.datetime(2014, 4, 5) > pdt
True
>>> datetime.datetime(2014, 5, 1) > pdt
True
>>> datetime.datetime(2015, 2, 1) > pdt
False
