Timeago - automatically updating fuzzy timestamps

Timeago is a jQuery plugin that makes it easy to support automatically updating fuzzy timestamps (e.g. "4 minutes ago" or "about 1 day ago") from ISO 8601 formatted dates and times embedded in your HTML.

Timeago - Features:

• Avoid timestamps dated "1 minute ago" even though the page was opened 10 minutes ago; timeago refreshes automatically.
• You can take full advantage of page caching in your web applications, because the timestamps aren't calculated on the server.
• You get to use microformats like the cool kids.
