The boundaries of time zones are defined with reference to a fixed line - the prime meridian. On the prime meridian, "midnight" is an important concept, marking the change of date.
A second of drift is negligible, but a minute of drift pushes the boundaries of time zones sideways by 6086 feet at the equator.

But having the average solar midnight match that very specific spot is not important. > A second of drift is negligible, but a minute of drift pushes the boundaries of time zones sideways by 6086 feet at the equator. Which doesn't matter when they're 60x that size wide. Especially when countries will shift an entire time zone for fun. A minute of drift is also negligible for civil time, as long as everyone is in sync, and we can't really predict the timekeeping future beyond that first minute of drift.
