[time-nuts] European grid phase heading back

Hello,

It looks like the European (ENTSOE) mains grid phase is now heading back
to what it was before the large deviation of February.
See my measurements at http://wwwhome.ewi.utwente.nl/~ptdeboer/misc/mains-2018.html
The ENTSOE website doesn't mention this correction yet, other than as a
future "step 2".

One can wonder how useful this correction is, though: just last weekend,
daylight savings time started in Europe, so most mains-driven clocks have
probably been manually set to the correct time on that occasion. Those will
soon be some 5 minutes fast...

Regards,
