It does not hold any tzinfo instance denoting UTC time. Note that the object created is still a “naive” object. The class method utcnow()of datetime class creates a datetime instance initialized with the current UTC time. # This will create a datetime object with current time and dateĭateWithCurrentTime = ()Ĭreating a datetime object from current UTC time: A tzinfo object can be passed inside now() if an “aware” object is required. The class method now() of Python datetime class creates a datetime instance with the current time and date. # This will create a datetime object with today's dateĬreating datetime object from current time and date: The above Python statement will create a datetimeObject from a tupe of values datetimeTuple.Ĭreating datetime object from today's date:Ĭreating a datetime object with today's date is done with invoking the today() class method of datetime class. # Create another datetime instance by unpacking datetimeTuple with splat operatorĭatetimeObject = datetime.datetime(*datetimeTuple) ![]() PstTimeDelta = datetime.timedelta(hours=-8) # Create a timedelta with the number of hours PST is behind UTC The splat operator * can be used to unpack a tuple as given in the python example below: TzObject = datetime.timezone(cstTimeDelta, name="CST")ĭatetimeObject = datetime.datetime(2017,2,22,12,55,55,99,tzObject)Ī datetime object can be created from a tuple of required values. # Create a timedelta with the number of hours CST is behind UTCĬstTimeDelta = datetime.timedelta(hours=-6) microsecond : with the default value of zero second : with the default value of zero minute : with the default value of zero The datetime constructor takes the following components and constructs a datetime object. Python datetime objects can be created using several ways. Similar to date objects datetime objects as well exactly have 86400 seconds in a day. Similar to date objects, which extend the Gregorian calendar, for pre-gregorian dates and future dates as well the datetime objects also extend to the pre-Gregorian dates and future dates. Since the datetime class can contain time zone information as well, date time instances are potential "aware" objects when compared to “naive” objects like date objects, which do not have time zone information. TimeZone - Either None or a valid tzinfo object.The Python datetime class represents the following information together: ![]()
