I was reading http://en.wikipedia.org/wiki/Planck_time and noticed a reference to: http://phys.org/news192909576.html where it is stated that:

12 attoseconds is the world record for shortest controllable time

This article is now almost 4 years old, is this still the record or is in the meantime this record broken?

It seems that we reached zeptosecond controllable time in 2021:

Using transient magnons, Physicists have tuned the quantum phase of a quantum system embedded in a solid with a precision of 1 zs and a timing stability below 50 ys. [1]
