> Apparently UDFHour.java does have two evaluate() functions. One that does accept a Text
object as parameter and one that does use a TimeStampWritable object as parameter. The first
function does return the value of Calendar.HOUR_OF_DAY and the second one of Calendar.HOUR.
In the documentation I couldn't find any information on the overload of the evaluation function.
I did spent quite some time finding out why my statement didn't return a 24 hour clock value.
> Shouldn't both functions return the same?
