No it's standardized. Outside of accidents the power providers take extreme care to keep the frequency synchronized to UTC. Exactly.

A clock using the power grid as reference might be off by 4 minutes over the day but on average it will be perfectly on time.

It used to be in the US that some operators would have a plain off-the-shelf alarm clock in the control room, and, in case the evening load made the frequency dip, operators would adjust things so that the clock would read 6am (for example) exactly the next day.
