We already have Invisibility Cloaks, now we get a Time Cloak

Invisibility cloaks are a very old fantasy thing to have. In the last couple of years scientists were actually able to create invisibility cloak experiments. Nothing even close to become a product, but in principle it works.

The Technology Review reports now that scientists at the Cornell University created a cloak for time. The experiment shows that for a very, very short time (110 nanoseconds), time is suspended. This means anything happening in that period is not recorded. It basically never happened. 

Is this the key to time travel? The scientists refrain from guessing what their time cloak could be used for enventually - it could also be a dead end. The Technology Review does a good job explaining the Time Cloak - understandable even for non-scientists.
