Earth Time Clock ver. 0.1 visualises current (or simulated) position of the Earth's surface in relation to the Sun (Solar Time). It shows view of the Earth from above the North Pole. Using control panel you can observe current or simulated Earth's position as well as Earth's rotation (play animation button).

- 'Play Animation' simulates UTC time flow according to combobox settings
- 'One Step' button moves the UTC clock one step ahead or backwards according to combobox settings
- Sets current time.

• 'Equinox Or Solstice' buttons - set simulated time to equinoxes or solstices to show Earth's illumination in different seasons.
  • Spring equinox (other names: Vernal equinox, March equinox or Northward equinox) - observed as early as March 19 or as late as March 22 (depending on year and timezone)
  • Summer solstice (other names: Estival solstice, June solstice or Northern solstice) - observed June 19-23
  • Fall equinox (other names: Autumnal equinox, September equinox or Southward equinox) - observed September 22-24
  • Winter solstice (other names: Hibernal solstice, December solstice or Southern solstice) - observed December 19-23
  Tip: to see how illumination of the Earth changes through the seasons, set 'step' to '+/-1 one day' or '+/- one week'
  
• 'Daylight Saving Time' checkbox - If switched ON, time in timezones table below the switch is adjusted one hour forward.
