CIA crypto-king offers new 'clock' clue to crack Kryptos code

The man who built a cryptographic sculpture for the CIA has provided a second clue to help crack its infamously difficult code.
Standing in a courtyard inside the CIA headquarters in Langley, Virginia, the last part of the Kryptos sculpture has remained unsolved for almost 25 years.
 
Now Jim Sanborn, its creator, has given a one word clue to this most intractable of cryptographic mysteries: the word "clock".
This follows a similar clue released four years ago, when Sanborn revealed that six of the letters translate to the word "Berlin".
The sculptor hinted that his latest tantalising clue refers to the famous Berlin Clock, which tells the time using the principle of set theory. In the picture below, it is showing the time as 10.31.
