Description

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
