At OpenSignal, each datapoint we collect has two timestamps: the time the reading was taken and the time the reading was inserted into our server. Because we make extensive use of SQLite cacheing on devices, these times can be far apart -- sometimes up to the order of weeks. Read More >>

Time cloaks are so much cooler than invisibility cloaks because they use freaking time to hide things, not silly dumb vision tricks. This new method of using a time cloak is the first that can cloak data at rapid rates. It might change security altogether. Read More >>

Did you know there's a clock on the BBC's home page? Well there is. That's it there in a screenshot. The problem is, it uses your PC's system time to display the time, so if your PC's set wrong so is the BBC's clock. And for that petty reason alone, it's going to be removed. Read More >>

We know that the universe is roughly 13.8 billion years old—give or take a few hundred million years. Which seems like a decently accurate reading. But a new pair of clocks, which can measure time at a 10^18 fractional level, makes our own measurements look like child's play. To have the same level of precision as these twin timepieces, we'd have to be able to specify the age of the known universe to within less than one second. Read More >>

If you overheard someone talking about time crystals in a bar, you'd think they were mad, or drunk. Or both. These things, theoretically, oscillate for eternity without any energy input whatsoever—and if that sounds like a perpetual motion machine, it's because it is. Impossible, right? But what if it was a Nobel prize-winning physicists making the suggestion? Read More >>

There's nothing to spice up your Monday like getting a feel for how insignificant of a speck you are in the grand scheme of the universe. Here Is Today does just that, but in such a pretty, minimalist way that you won't even mind. Read More >>

How will the future look back at 2013? Will they be in awe of the sheer number of hours we spent on the Internet, just like we're in awe of the cast of Mad Men drinking and smoking? Will they be in disbelief that many people spent most of their waking hours in front of a computer? Read More >>

A surprising number of nerds made it on to the shortlist for this year's Time person of the year award. More than the others, though, Tim Cook has clearly made a lasting impression outside the tech community -- demonstrated by him nabbing second place. Read More >>

No matter what's going on in your life today, there's always something else around the bend, something to anticipate or dread. This countdown clock helps you keep your hopeful sights on the former. Or the latter if you're a masochist. Read More >>

What is that there? I can't see anything. Oh wait it's a clock. Just like the reptile it's named for, Chameleon Clock captures the scenery behind your screen and overlays the time on top. Read More >>

We live in a base-10 world. The decimal system governs everything from the binary functions of computers to the amount of change you get when you buy a Mashed Potato Slurpee. So why isn't the standard Earth day just 10 hours long? Credit the Egyptians for that one. Read More >>

To anyone who is good at making stuff with their hands: please make me this DeLorean center console clock from Back to the Future for me. There are instructions from Adafruit and links to all the stock parts you need to pull it off. Read More >>

Over at Instructables, SelkeyMoonbeam has figured out a clever way to make one analogue clock tell the time of 24 different time zones. All you have to do is turn the clock's base to the city (or time zone) you're in, and the clock will show the right time. Read More >>
