Subject RE: [lang] DateUtils round and truncate functionality with Calendar.AM_PM
Date Sun, 03 Aug 2003 23:45:46 GMT
I don't know that rounding to AM_PM makes sense. I'm having a difficult time
coming up with any rounding scenario that makes sense. I think it makes
sense to say that the boundary is 12:00PM, and that times before that value
cause round down, and times after that value cause round up.

But what does "round down" mean? What does "round up" mean? Maybe someone
who has a use case for this functionality can provide a good suggestion.
