Time Zones
Description
At this category you can convert a particular date/timestamp from one
timezone to another. The daylight saving times rules that can apply to a
country at that time are being taken into account.
Select a timezone and enter a source date/time. Select the target timezone
and get the result.
In addition to the target time also the time difference is being calculated.
Distances are being printed as km if both timezone ids represent a city. In
the example below there are 9 hours difference between the two timezones
Europ/Berlin and America/Los_Angeles. Since both timezone IDs represent
cities, also the distance between the center of Berlin and the center of Los
Angeles is being printed, that is 9,303.48 km. The data that is being used
to calculate the distance comes from the public domain timezone database.
Greyed out Timezone IDs
Timezone IDs printed in gray text are those that were valid in the past and
have been replaced by new ones (actually it is exactly that one which can be
found above the current entry). For example "Israel Standard Time" has been
replaced by Asia/Jerusalem.
Scope
Zeiten
sind entsprechend den Regeln des gewählten Landes der Oberfläche
einzugeben. Für Deutsch bedeutet das das Format: TT.MM.JJJJ HH:MM:SS.
Zeiten ab dem 15.10.1582 werden als Datum des Gregorianischen
Kalenders interpretiert, davor als Datum des Julianischen
Kalenders. Das kleinste (theoretisch) erlaubte Datum ist der
01.01.0001. Das NumericalChameleon erlaubt die Berechnung
zwischen allen Zeitzonen zu allen Zeiten, auch wenn es einige
Zeitzonen-IDs bzw. deren Länder noch gar nicht so lange gibt. Die
Sommerzeit wurde z. B. auch erst im Jahre 1916 von einigen wenigen
Ländern eingeführt. Für Jahreseingaben jenseits des Jahres 9999
wird keine Garantie übernommen.
Timezone database outdated?
The
timezone database is provided by the Java Runtime Environment
(JRE). Please use the latest JRE, respectively update your JRE by
the latest timezone updater in order to use the latest timezone
database. Note that the timezone updater is a tool that is provided by
the vendor of your JRE. A little icon in the right lower right corner
appears if you select the timezone category and the timezone database
is outdated.
If you click on that little symbol, you get more information. Example:
Also the update Center helps you to identify both the installed time zone
database version and the available time zone database version. If you double
click on the Time Zone Database row, you can update the time zone database.
