Time Zone
Retired university lecturer
Heiner Thiessen is member of the BSS (British Sundial Society) and designer
of unique equatorial sundials that tell the time for all longitudes (and timezones)
around the world simultaneously. His educational sundials require hands-on action
and tell the time of sunrise and sunset. They can also read solar declination,
and even show the geographical point of solar zenith at the time of observation.
His unique sundials are ideal for garden, courtyard, park, learning centre,
school, college or university in the UK or anywhere else around the world. They
are an educational resource that mirrors the earth's orbit (or the apparent
movement of the sun around Earth) within the solar system, harnessing the simplicity
of solar power and solar energy to accurately tell the time in all time zones
around the world from the Greenwich Meantime Meridian (gmt) to the International
Date Line. Just dial up to read local apparent time for your own local meridian
with these hands-on shadow clocks. This website includes educational software
that demonstrates an apparent solar rotation. Solar Time is based in Petersfield,
Hampshire,UK
