  # A Timezone is unambiguously defined by the set of time
  # measurement rules determined by the governing body for a given
  # geographic area. These rules describe at a minimum the base offset
  # from UTC for the time zone, often referred to as the Standard Time
  # offset. Many locations adjust their Standard Time forward or backward
  # by one hour, in order to accommodate seasonal changes in number of
  # daylight hours, often referred to as Daylight  Saving Time. Some
  # locations adjust their time by a fraction of an hour. Standard Time
  # is also known as Winter Time. Daylight Saving Time is also known as
  # Advanced Time, Summer Time, or Legal Time in certain countries. The
  # following table shows the changes in time zone rules in effect for
  # New York City starting from 1967. Each line represents a description
  # or rule for a particular observance.
