That's nothing. Time zones alone already create significantly larger errors. Belgrade and Sevilla share a time zone, but the solar meridian ("noon" on a sundial) is 12:44 in Belgrade and 14:30 in Sevilla. Obviously, the same error is present in the astronomical "middle of the night". This does not, in fact, create "legal issues" for Serbs or Spaniards.
In 600-1000 years, around the time that it would actually matter, we're going to have to reform the time system anyway to account for relativistic drift between the surface of the Earth and human settlements elsewhere in the solar system.
