Several years ago (c. 1980) I remember an occasion when the local utility slipped about 20-25 minutes of effective 'time' over the course of one night.
I didn't know much about power grids then, except that they existed, and contributed to certain power blackouts. But what happened was that the local utility had gotten disconnected from the rest of the northeast USA grid, and free-ran overnight at a significantly offset frequency. I think it would have been running at around 57 Hz or lower.
