  Converts Universal Time Coordinated (UTC) date and time to local
  date and time in the form [;;4m{{Year, Month, Day}, {Hour, Minute,[0m
  [;;4mSecond}}[0m if supported by the underlying OS. Otherwise no
  conversion is done, and [;;4mUniversaltime[0m is returned. Example:

    > erlang:universaltime_to_localtime({{1996,11,6},{14,18,43}}).
    {{1996,11,7},{15,18,43}}

  Failure: [;;4mbadarg[0m if [;;4mUniversaltime[0m denotes an invalid date and
  time.
