About time in Europe Poland Warsaw
A system database of timezone information includes the offset from UTC and rules that indicate the start and end dates for daylight saving in each zone
Application software is able to calculate the time in various zones.
Terminal Servers allow remote computers to redirect their time zone settings to the Terminal Server so that users see the correct time for their time zone in their desktop/application sessions
Terminal Services uses the server base time on the Terminal Server and the client time zone information to calculate the time in the session.
While most application software will use the underlying operating system for timezone information, the Java Platform, from version 1.3.1, has maintained its own timezone database
This database will need to be updated whenever timezone rules change.
Sun provides an updater tool for this purpose.
As an alternative to the timezone information bundled with the Java Platform, programmers may choose to use the Joda-Time library.
There is very little in the way of timezone support for Javascript
Essentially the programmer has to extract the UTC offset by instantiating a time object, getting a GMT time from it, and differencing the two
This does not provide a solution for daylight savings variations.
The DateTime objects and related functions have been compiled into the PHP core since 5.2
This includes the ability to get and set the default script timezone, and DateTime is aware of its own timezone internally
PHP.net provides extensive documentation on this.
As noted there, the most current timezone database can be implemented via the PECL timezonedb.
The standard module datetime stores and operates on the timezone information class tzinfo
The third party pytz module provides access to the full tz database.
Negated time zone offset in seconds is stored time.timezone and time.altzone attributes.
Each Smalltalk dialect comes with its own built-in classes for dates, times and timestamps, only a few of which implement the DateAndTime and Duration classes as specified by the ANSI Smalltalk Standard
VisualWorks provides a TimeZone class that supports up to 2 annually recurring offset transitions, which are assumed to apply to all years (same behavior as Windows time zones.) Squeak provides a Timezone class that does not support any offset transitions
