  Notes:
  Coordinated Universal Time (UTC) has time zone designator "Z" and is essentially the same as Greenwich Mean Time (GMT)
  Hawaiʻi Standard Time (HST) is 10 hours behind UTC, i.e. 11:00:00 UTC is 01:00:00 HST

  The Approximate Local Time calculation is based on longitude only,
  i.e. 15 degrees of longitude per hour (Nautical time),
  it does not completely coincide with government selected time zone regions used on land.

  Here is a list of UTC time offsets for converting to your time zone.
