Telling the time one planet at a time.

Alexander Avtanski designed a clock that can be adjusted to keep time on many different planets based upon each one’s rotation period — at the same time. Here’s what sets this clock apart from other extraterrestrial clocks, according to its builder…

  • It has 16 timers that can be independently paused and restarted, and can run forward or backward.
  • There are 16 alarms with configurable sounds and actions.
  • Timers can show Earth, Mars, Jupiter, etc. times at the same time.
  • How about sidereal time, Moon phase, Jupiter’s Great Red Spot transit time, and anything periodic in general?
  • Avtanski provides comprehensive building instructions at the link.
