"Nearly every second, a user on Twitter tweets about what time it is." Chirpclock makes use of this as an interesting way of keeping track of the time.

Timepieces! Ancient calendars, ancient clocks, beautiful clocks, atomic clocks and the clocks built into your brain that determine how you perceive time and form memories. All the good stuff is inside: [more inside]

Internet Clocks, Counters and Countdowns

The cable clock. This clocks tells time, just like any other clock, but the movement of the hands is hypnotic and beautiful. To physicists, time is defined by quantum mechanics. A photon with energy h (Planck's constant) behaves as though it were oscillating once per second. For Philosphers, time is less concrete, and they love to talk about it. Western society lives by the clock - does it make a difference if this is the kind of clock that you live by? After all, everyone knows that time is money. If you have to be a clock watcher, does it help if the clock is as calming as the Cable Clock is?

Does anybody really know what time it is? If anybody really cares, the NIST is the place to go for not only the answers (including a list of government operated open access NTP servers), but more information than you probably ever wanted to know about standard time.

Stolen shamelessly from Tom: a charming clock, reminding us once again that "time" is an intellectual concept meaningless without human participation... (Don't miss the webserver, either.) Considering the depth and breadth - and apparent copious free time - of the MeFi community one would hope we'd be able to help fill in some of the still unphotographed minutes.
