Extension:TimeZoneInfo

What can this extension do?
This extension displays several types of useful (?) information relating to timezones. It is expected to be of some use in Wikis which serve a distributed community of users, where people want to know what time it is for other people.

Usage
The extension creates three new tags:


 * creates a timezone conversion chart
 * displays standard <--> daylight time transitions
 * produces a table of all known timezones

Time Zone Chart
The  tag creates a conversion chart showing the relationships between a number of specified timezones. Timezones with fractional hour offsets (eg. India) are handled quite well.

The tag takes the following parameters:
 * align='' tag displays a table of standard <--> daylight time transitions for a number of specified timezones, making it easy to see when people in other countries will be changing their clocks.

The tag takes the following parameters:
 * align='' tag produces a table of all known timezones, or zones whose names match a specified filter.

The tag takes the following parameters:
 * filter=  : if supplied, only zones whose name contains the given string are shown.

Any text enclosed within the tag is ignored.
