 def parse_date(date_string):
 """ Parse the given string as datetime object. This parser supports in almost any string formats. For relative times, like `10min ago`, this parser computes the actual time relative to current UTC time. This allows time to always be in UTC if an explicit time zone is not provided. Parameters date_string : str String representing the date Returns ------- datetime.datetime Parsed datetime object. None, if the string cannot be parsed. """
