Dmitriy V. Ryaboy commented on PIG-1430:
----------------------------------------
I think int vs long doing different things is dangerous.
iirc ISO specifies to the second, so getting an int or a long should assume
seconds.
I suggest implementing a duplicate set of functions for millisecond timestamps
that actually have "Ms" in the name (and of course a set of sec to millisec and
sec to millisec and both to ISO conversions :-).

> All functions in
> contrib.piggybank.java.src.main.java.org.apache.pig.piggybank.evaluation.datetime
> should seamlessly accept integer Unix/POSIX times, and return Unix time
> output when given an int, and ISO output when given a chararray.
> Note: Unix/POSIX times are the number of seconds elapsed since midnight
> proleptic Coordinated Universal Time (UTC) of January 1, 1970, not counting
> leap seconds. See http://en.wikipedia.org/wiki/Unix_time
