How can I convert these

Answer 1

I used this for changing a Juian date to xml xsd:datetime

def julianDate2ISO8601(d, offset='+00:00'): """ return ISO8601 formated datetime from julian date optional offset [+|-]hh:mm """ d = str(d) # make sure it is a string # replace leading number with correct century centuryArray = ['19','20','21'] d = centuryArray[int(d[:1])] + d[1:] # format string to iso 8601 datetime return datetime.datetime.strptime(d, '%Y%j').date().strftime( '%Y-%m-%dT00:00:00') + offset
