Jonathan Coveney updated PIG-1431:
----------------------------------
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).
