“The Future of UTC Conference” will be held at the University of VA from 29-31 May 2013 in Charlottesville VA, and Harlan Stenn will be presenting a paper there.
For most of our history, we’ve considered a “day” to be a solar day, and a “year” to be the time it takes the earth to rotate around the sun. We’ve even gone to some pains to mark the seasons accordingly, noting the vernal and autumnal equinoxes and the longest and shortest days of the year.
Over the course of history, we’ve noticed that our calendar doesn’t quite match with reality. Continue reading »
Network Time Foundation is pleased to have been chosen as a mentoring organization for Google’s 2013 Summer of Code project. This will be the sixth consecutive year that Network Time has been fortunate enough to be selected for the GSoC program.
This year, nine students have submitted proposals to work with us. Google will announce the accepted project proposals on 27 May 2013.
NASA’s Curiosity Rover has landed on Mars. A lot of time an effort has gone in to scheduling what will be done there, when it will be done, how much time it will take, etc. The work there is done at specific local (Mars) solar time, and the Martian day is 24 hours and 39 minutes long. For the people doing experiments, that means their day shifts “later” by 39 minutes every day. But prefer a 24 hour day with 60 minute hours, so they have special clocks that keep “martian time”.

I was visiting a friend in the hospital a few months ago. She had a medicated IV drip line (an infusion pump) that allowed precise tuning of how much “stuff” was administered. If it knew that it was dosing at, say, 50ml/hour and it had a 500ml bag then it would need to be changed out in 10 hours’ time and would alert accordingly. It would also alert if it detected that something was wrong with the flow rate. Continue reading »
Google has again selected mentoring organizations for their 2012 Google Summer of Code™ and NTF is very pleased to be participating, and has two Network Time related efforts this year: NTP and PTPd.

We’d like to participate in 2013 as well. So if you are a student who might be interested, please find a project and talk to us – we’re happy to work with you to help you with a proposal for next year!
A new clock is coming to town, and it’s 100 times more stable than the best atomic clocks we have right now – it should keep time to within 1/20th of a second for 14 billion years, the age of the Universe. Continue reading »
I suspect very few people think about how long a day is, and of that number, fewer still wonder if the length of a day changes much, or what sort of things affect the length of the day. Continue reading »
I saw a facebook update by Peter Thoeny, where he posted a link to an article about how executives can lead more effectively by being community managers. I read it and liked it, so I thought I’d share it as well.
I was looking for articles about really accurate clocks (OK, I’m using ‘accurate’ colloquially[nbnote ]http://en.wikipedia.org/wiki/Accuracy_and_precision[/nbnote]) and came across this one from late 2007, about “How Super-Precise Atomic Clocks Will Change the World in a Decade” and I was just intrigued by some of the things I saw in there.

Raymond Veloz had exited his vehicle after getting into a minor accident with another motorist around 7:30 a.m. on Tuesday, Dec. 7, 2010. He was standing near the other driver’s vehicle exchanging information when he was struck by Araceli Beas, as reported by CBS News.
Raymond Veloz’s daughter filed a wrongful death suit claiming that Araceli Beas’ Facebook page showed an update posted at 7:54 a.m. on Dec. 7, the same time that Veloz’s cell phone records showed a call being made to 911.
Beas’ mother came to her daughter’s defense claiming that she posted the Facebook update as she sat in her car while waiting for it to warm up outside her boyfriend’s home two miles away from where the crash occurred, reports The Chicago Tribune.
