If a timezone aware datetime object is passed, it is returned unmodified. If a native datetime object is passed, it is given the specified timezone. If the input is a string, it is parsed as a datetime with the given timezone. Date strings are accepted in three different forms: date only (Y-m-d), date with time (Y-m-d H:M:S) or with date+time with microseconds (Y-m-d H:M:S.micro). Additionally you can override the time zone by giving a specific offset in the format specified by ISO 8601: Z (UTC), +HH:MM or -HH:MM. :param str|datetime input: the datetime or string to convert to a timezone aware datetime :param datetime.tzinfo tz: timezone to interpret ``input`` in :param str arg_name: the name of the argument (used in an error message) :rtype: datetime NzInvalid date stringr Zcss|]}t|VqdSNr-).0xrrr sz&convert_to_datetime..:r+<cSsi|]\}}|t|pdqS)rr-)rOkvrrr sz'convert_to_datetime..zUnsupported type for %s: %szEThe "tz" argument must be specified if %s has no timezone information)Zis_dstzOOnly pytz timezones are supported (need the localize() and normalize() methods))r<rrcombinerrGrH _DATE_REGEXmatchr@ groupdictpopr splitritemsrJrLr*rr rDAttributeError) inputtzZarg_nameZ datetime_mvaluestznamehoursminutessignrrrrpsF         rcCs"|dk rt||jdSdS)zf Converts a datetime instance to a timestamp. :type timeval: datetime :rtype: float Ni@B)r utctimetuple microsecond)timevalrrrrsrcCs|dk rt|tSdS)zp Converts the given timestamp to a datetime instance. :type timestamp: float :rtype: datetime N)r fromtimestampr ) timestamprrrrsrcCs"|jddd|j|jdS)za Converts the given timedelta to seconds. :type delta: timedelta :rtype: float rVg.A)daysseconds microseconds)deltarrrrsrcCs"|jdkr|td|j dS|S)zQ Rounds the given datetime object upwards. :type dateval: datetime rrR)rqrr)rkrZdatevalrrrrs rcCs|r|dSdS)Nz%Y-%m-%d %H:%M:%S %ZNone)strftimertrrr datetime_reprsrwcCst|dr|jSt|ddp&t|dd}|rJt|drJt|rB|n|j}n t|dd}|rtt|drtd|j|jfSt|drt|dr|jS|jjStd |dS) zd Returns the best available display name for the given function/callable. :rtype: str r,__self__Nim_selfr*im_classz%s.%s__call__z@Unable to determine a name for %r -- maybe it is not a callable?)rIr,getattrr rLr*rJ)rf_selfZf_classrrrrs    rcCst|trtdt|}d|kr*tdd|kr:tdt|r~t|dr\|jr\|jj}qt|drv|jrv|jj}q|j}n|j}d||fS) z Returns the path to the given callable. :rtype: str :raises TypeError: if the given object is not callable :raises ValueError: if the given object is a :class:`~functools.partial`, lambda or a nested function z(Cannot create a reference to a partial()zz%Cannot create a reference to a lambdazz.Cannot create a reference to a nested functionryrzz%s:%s) r<r r@rr rIryr+rz)rCnamemodulerrrrs   rcCst|tjstdd|kr$td|dd\}}zt||gd}Wn tk rftd|YnXz |dD]}t ||}qt|WSt k rtd|YnXd S) zH Returns the object pointed to by ``ref``. :type ref: str zReferences must be stringsrSzInvalid referencerR)fromlistz5Error resolving reference %s: could not import module.z5Error resolving reference %s: error looking up objectN) r<rGrHrJr@r_ __import__ ImportError LookupErrorr| Exception)ref modulenamerestrCr~rrrr !s  r cCst|ts|St|S)z Returns the object that the given reference points to, if it is indeed a reference.
