Hello!
I'm currently working on a climatological dataset that uses unix-timestamp and a real date like 28/03/2004 02:45:00 h. in spring the unix-timestamp follows its continuos mode but in the column of the real date the time jumps one hour forward (e.g. from 1:59:59 to 3:00:00). i think this is...

Data::ICal::Entry::TimeZone::Standard(3pm) User Contributed Perl Documentation Data::ICal::Entry::TimeZone::Standard(3pm)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

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.
