The sun globe
A clock indicating the tempo of the passing sun, operating to the order of a sundial.
The Tempometer is a clock which displays the time of the user representing the tempo of the locally passing sun. From this one is able to have, instead of the politically/centrally determined standard-time, the scientifically/astronomically determined local, true, solar time of nature in front with planning one's activities.
Restoration of the dynamical, natural consciousness of time that with the standard time of means, zones and summertimes was lost. Thus one with the Tempometer has the opportunity to recover from one's estrangement relating to nature and has thus the chance to regain one's, from the stress-society lost, synergy with oneself and one's fellow man.
Practical, technological reality:
The clock by history since the eighteenth century confined to a museum in Paris, France, was for the first time implemented on the internet the 10th of Nov. 2005. It can be downloaded for researchers and for interested webmasters to implement at their site. The download offers nine files in the folder. These are php-files to separately deal with php and html, two php-pages to compute the day corrections to the equation of time and a page with help-functions. The notimeserver-page is an error-page also to be installed. As the daily corrections around 2023 run invalid and an upgrade is needed, must this daycorrection.php-file be adapted. The two html-pages can, once loaded to the internet, be summoned to compute solar time.
The program of the clock sets the Tempometer to the sun with the help of the by the user entered longitude in degrees and minutes belonging to the place where the computer is situated (for the user to check out on: Geographical Position). This setting is done with the help of the equation of time (see also The Full calendar of Order). This is a table indicating the degree to which a normal clock qua tempo runs ahead or behind of the sun. Solar time is always: GMT + longitude x 4 min. - EqoT. for eastern longitudes and GMT - longitude x 4 min. - EqoT for longitudes west of Greenwich. To perform the computation is the GMT, the mean time GMT of Greenwich fetched by the program from http://www.ntp.org/ (see also: Greenwich mean time; notice: the Tempometer offers in a leap-year with a 29e febr. a normal shift of values of one day, with an extra value of 2.43 for the 31 Dec.). The meter operates correctly if the indication of 12 o'clock on the meter is in accord with 12 o'clock on a sundial - the sun in the exact south. The time-indication in the Tempometer-field runs to the sun, but a standard-time-clock corrected with it can show a deviation of half an hour maximum over four months (from the 2 Nov. to the 2 febr.). For that reason must standard-time clocks at least once a week be corrected if one wants to keep them to the sun. With a clock thus corrected the natural tempo of the time-indication is restored that since the political/pragmatical, horological introduction of mean time for mechanical clocks was lost. Once in twenty-four years (24.23 year) the phase of the equation of time - the phase of 1683 lags about 13 days behind the one of 1998 - must with one day be shifted ahead (the entire table thus), in order to accurately do justice to the time of mother nature. Ultimately standard time is derived from the solar time of the Tempometer and not the other way around. --rpba 12:57, 8 May 2006 (UTC)
