The Twitter version of Marclay's The Clock MAR 19 2012
Chirp Clock finds tweets containing the current time and displays them on the site.
Nearly every second, a user on Twitter tweets about what time it is. It could be groaning about waking up, to telling a friend when to meet, to an automated train scheduler altering when the next one is coming. By searching Twitter for the current time we get a tiny glimpse of how active and far reaching the social network is.
