Bruce.... WIKI : "The Romans numbered the morning hours originally in reverse. For example, "3 a.m." or "3 hours ante meridiem" meant "three hours before noon", compared to the modern usage of "three hours into the first 12-hour period of the day".[citation needed]"

That should clear it up. The Romans did it.
