----------------------------------

    Attachment: PIG-1431-0.patch

I bet you never thought you'd get a patch for this, Russell :) Now that we have a DataTime datatype in Pig, it seems totally reasonable to have a NOW(). The time will be the default DateTime object (unix epoch, iso chronology), and it will be _as of the moment the object is created on the front-end_. All values from the same instantiation of NOW() will be equal, though we should add tests etc to make sure this is the case.

I whipped this up quickly to see if the strategy I thought would work would work. It did (as far as I can tell).

> Need a NOW() for getting datetime diffs between now and a prior or future date.  Will use the system timezone.  Will make one for ISO datetime and one for Unix time.
