Seems like there's plenty of deviation in North America, more even than the European grid is complaining about. Quebec and the Maritimes seem to oscillate between low and normal, and the west seems to always be a bit too fast.

Yeah you're seeing the short term variation at that site, and there's plenty of it. But over a 24 hour period - for now anyway - NERC standards require time error correction, http://www.nerc.com/files/BAL-004-0.pdf

Going forward it may not be a good idea to rely on the grid's timebase as there's talk as well as an NPRM out there to do away with the standard. https://www.federalregister.gov/documents/2010/03/29/2010-64...
