Agreed, I'm thinking purely of displayed time.  Where the utility of 
using times like 2400 and 2530 is purely the convenience of people 
looking to catching a bus after a late night out.

The 24:00 time should be referred to in a similar way to the notation of 
'0+' in limits (that is informally defined as the smallest positive real 
number -- formally that is nonsense, 'lim 0+' actually means approach 
the limit from the positive direction).
