Having said that, I agree that we should adopt the 24-hour clock so as to avoid confusion.
But even the 24 hour clock has its confusables. Do you call 12 midnight ‘0000’? or ‘2400’? Railway timetables usually skirt the issue by calling it 2359 and then let the train leave a minute late.

Originally posted by Bryn View PostWhen it comes to recording time, we are dealing with simple cardinals from 1 to 12 or 1 to 24, with Meridiem being covered by 12 in either system. In the 12 hour system, it becomes necessary to introduce some way of indicating whether, by 12, one is referring to midday or midnight. To refer to midday as being after midday makes no sense, as does referring to it as before midday. If using the 12-hour system, a.m. and p.m. simply do not make sense when dealing with noon and midnight themselves. "12 noon" and "12 midnight" resolve this anomaly.
“Greater” is just a word - might as well be “blob”. It means whatever one wants it to mean. Conventional terms for time relations include before, after, later, sooner etc.
