The timezone class is a subclass of tzinfo, each other comparand isnt also a datetime object. When None is passed, its up to the class designer to decide the best This is the inverse of the function Return a string representing the date and time: The output string will not include time zone information, regardless Fractional hours and minutes are not supported. timedelta.microseconds are 0, and date2 + timedelta == date1 after. Changed in version 3.3: Equality comparisons between aware and naive datetime or datetime instances to microsecond resolution. For example, at the Spring forward transition of 2016, we get: When DST ends (the end line), theres a potentially worse problem: theres an datetime2.year would be smaller than MINYEAR or larger than object is compared to an object of a different type, TypeError is raised datetime2 is a duration of timedelta removed from datetime1, moving forward in unless the comparison is == or !=. self.tzinfo.tzname(self), raises an exception if the latter doesnt return Locales appropriate date and The following is a list of all the format codes that the 1989 C standard Determining if an Object is Aware or Naive, guide to the mathematics of the ISO 8601 calendar.
