A well circulated piece of trivia is that 1972 was the longest year in
recorded history because civil time contained two leap seconds.
I offer this challenge:
What was the second longest year in recorded history, and how many
leap seconds did it have?

Clearly the longest year in any contemporary calendar will fall into
the category of one of the luni-so
arity, coordinated on the Internet.
The festival takes place on the leap second @ 30th June 2012
23:59:60 UTC. During that second all the works are exhibited and
performed.
Call for entries: Works lasting one second or less. The festival
