UTC is civil time. Civil time is used to express deadlines. Most deadlines fall at the end of a calendar day, so which day the 61st second falls in will only affect a few time zones, but deadlines may fall on other hour boundaries. So it is necessary to know which hour the 61st second belongs to, and I believe it belongs to the hour that is about to end.
