This has been making rounds for quite awhile, I am surprised it has not been
picked up here.
Frequency deviations in Continental Europe including impact on electric clocks
steered by frequency
Continental European Power System has been experiencing, since mid-January,
continuous significant power deviations due to shortage in supply from one
transmission system operator of the interconnected system. All actions are
taken by the TSOs of Continental Europe and by ENTSO-E to resolve the situation.
The power deviations have led to a slight drop in the electric frequency. This
in turn has also affected those electric clocks that are steered by the
frequency of the power system and not by a quartz crystal: they show currently
a delay of 5 minutes. TSOs will set up a compensation program to correct the
time in the future.
