What if you're keeping track of time to seconds?
Is "one second after midnight" _really_ part of the previous "day"?
What about the middle of the day?
Is "one second after mid-day" (12:00 noon) really still part of the 'morning'?
I'll agree that there is an ambiguity about whether 'midnight' is part of the preceeding or succeeding day. I will, however, argue that if it is any interval _past_ "midnight" -- be it a minute, a second, a millisecond, a micro-second, a femto-second, or any smaller interval -- that there is no question that the time-tick is in the 'new', not the 'old' one.
