Julien Le Dem reopened PIG-3014:
--------------------------------


I see a failing test:
org.apache.pig.test.TestBuiltin.testConversionBetweenDateTimeAndString

java.lang.NullPointerException
	at org.apache.pig.builtin.CurrentTime.exec(CurrentTime.java:41)
	at org.apache.pig.test.TestBuiltin.testConversionBetweenDateTimeAndString(TestBuiltin.java:450)

                
> CurrentTime() UDF has undesirable characteristics

> As part of the explanation of the new DateTime datatype I noticed that we had added a CurrentTime() UDF. The issue with this UDF is that it returns the current time _of every exec invocation_, which can lead to confusing results. In PIG-1431 I proposed a way such that every instance of the same NOW() will return the same time, which I think is better. Would enjoy thoughts.
