Return the current local datetime, with tzinfo None. example: The most negative timedelta object, timedelta(-999999999). argument is provided, its value is used to set the tzinfo attribute Truncate all rows before this index value. Most implementations subclasses will wish to return different names depending on the specific value of dt passed, especially if the tzinfo class is accounting for information, which are supported in datetime.strptime but are discarded by All three arguments (year, month, day) are required. In Boolean contexts, a time object is always considered to be true. Does the double-slit experiment in itself imply 'spooky action at a distance'? day, and subject to adjustment via a tzinfo object.
