This is a more complex version of Janne's original CurrentTimePlugin. I had a problem with the original where my server was on the West Coast and I needed the current time on the East Coast. So, I altered the plugin to support timezones, chosing date and/or time display, and the level of detail in what was reported. This plugin is not a drop-in replacement for the original, since I had to abandon the SimpleTimeFormat class that the original used internally.

This plugin was developed under JSPWiki 2.1.85 CVS/JDK1.4.2, and I haven't tried it anywhere else. Let me know if I should make any changes for compatability reasons.

Usage:

   [{INSERT net.colbadhombre.JSPWiki.plugins.CurrentTimeDatePlugin WHERE timezone='US/Samoa' content='date' format='medium'}]

Parameters:

The source code is below and a JAR is attached at the bottom. The JAR also contains the full source, including test code. The source has no copyright. Feel free to use it whereever and however you'd like.
