I thought I knew plenty about rainbows – they exist because the different colors of light bounce around differently inside the water droplets –and they can be explained by a simple formula that was discovered a few hundred years ago. But one day last year, when I was met by a beautiful rainbow outside the Masterclock headquarters, it got me intrigued. I quickly learned that there was a lot more to heaven and Earth than was dreamt of in my philosophy.

Nothing epitomizes the creative genius like Albert Einstein. In 1905, Einstein published four landmark papers which would become the foundation for modern physics. Ten year later, Einstein introduced his theory of general relativity. It wasn’t until 1971, however, that this theory of general relativity could finally be proven as an indispensable fact—thanks to advancements in the atomic clock and an airborne experiment conducted by physicist Joseph C Hafele and astronomer RIcharad E Keating.

In June 2021, the media made much of an unclassified Air Force report on what are now called Unidentified Aerial Phenomena (UAPs), better known as UFOs. Read the take of Dr. Demetrios Matsakis, Chief Scientist at Masterclock.

Will We Have a Negative Leap Second?

Mar 5, 2021

Modern society, of course, has decided that the Sun doesn’t orbit and the Earth turns. But we still pay a price for pretending it turns uniformly. That price is paid every few years, when the international timekeeping community slips in a leap second and time stops, figuratively speaking.

October 22, 2021 NOTICE

Masterclock GMR1000, GMR5000, NTP100-GPS (HS) along with older-generation Masterclock GPS devices HAVE NOT beEN affected by the October 24, 2021 GPS Daemon (GPSD) Rollover Bug. These Masterclock products do not use GPSD.

Critical Infrastructure (CI) owners and operators, and other users who obtain Coordinated Universal Time (UTC) from Global Positioning System (GPS) devices, should be aware of a GPS Daemon (GPSD) bug in GPSD versions 3.20 (released December 31, 2019) through 3.22 (released January 8, 2021). On October 24, 2021, Network Time Protocol (NTP) servers using bugged GPSD versions 3.20-3.22 may rollback the date 1,024 weeks—to March 2002—which may cause systems and services to become unavailable or unresponsive.

CISA urges affected CI owners and operators to ensure systems—that use GPSD to obtain timing information from GPS devices—are using GPSD version 3.23 (released August 8, 2021) or newer.
