Data::ICal::Entry::TimUsereContributedData::ICal::Entry::TimeZone::Standard(3)

NAME
       Data::ICal::Entry::TimeZone::Standard - Represents a Standard Time base
       offset from UTC for parent TimeZone

DESCRIPTION
       A time zone 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.

	    Effective Observance Rule

	    Date       (Date/Time)	       Offset  Abbreviation

	    1967-*     last Sun in Oct, 02:00  -0500   EST

	    1967-1973  last Sun in Apr, 02:00  -0400   EDT

	    1974-1974  Jan 6,  02:00	       -0400   EDT

	    1975-1975  Feb 23, 02:00	       -0400   EDT

	    1976-1986  last Sun in Apr, 02:00  -0400   EDT

	    1987-*     first Sun in Apr, 02:00 -0400   EDT

       Note: The specification of a global time zone registry is not addressed
       by this document and is left for future study.  However, implementers
       may find the Olson time zone database [TZ] a useful reference. It is an
       informal, public-domain collection of time zone information, which is
       currently being maintained by volunteer Internet participants, and is
       used in several operating systems. This database contains current and
       historical time zone information for a wide variety of locations around
       the globe; it provides a time zone identifier for every unique time
       zone rule set in actual use since 1970, with historical data going back
       to the introduction of standard time.
