Standard Time is a performance project by Mark Formanek which he has built in different cities. Carefully choreographed builders change a huge wooden digital clock in real time. For more films and information click here.

There is also The Human Clock which shows photos people have submitted of the time, in real time. It is worth a visit as some of the pictures are great (it becomes a little addictive waiting for them to change).

And I posted about Christian Marclay’s peice The Clock back in July when Jamie Kenyon from the Glasgow Centre of Contemporary Art told me about it
