There are a few things here, mostly related to Dark Ages.

Temuairan Time Converter - Convert a regular (that is to say, Gregorian) date to Temuair Standard Time, or vice versa.

Aosdic Clock - A web-based clock that can be put on webpages. The clock will display the correct time in Temuair to within a few Temuairan days.

You may also be interested in my local documentation archives. These archives contain manuals and other information for a wide array of subjects, including languages, an archive of RFC's, HTML/XHTML specifications, Internet services & daemons and more.
