Thejas M Nair commented on PIG-1314:
------------------------------------
bq. Are we discussing a user-facing API, or an internal storage mechanism?
Some questions were about interface, some about internal storage.
bq. Regarding the interface, presenting integers to a user as an interface
seems wrong to me.
Converting dates to integer is something user can optionally do, this is not
expected to be a common use case. String representation of date literals will
also be supported. Most operations will be on date type itself, without
converting it to int/string.
bq. Excluding certain timezones in the name of efficiency also seems wrong to
me.
All timezones supported by JodaTime will be supported. I was only proposing
that we encode the timezone info efficiently, at least for most likely used
ones. I think converting the string timezone (location name) to UTC offset in
minutes, is one possibility.

> Project: Pig
> Issue Type: Bug
> Components: data
> Affects Versions: 0.7.0
> Reporter: Russell Jurney
> Assignee: Zhijie Shen
> Labels: gsoc2012
> Attachments: PIG-1314-1.patch, PIG-1314-2.patch, joda_vs_builtin.zip

> Original Estimate: 672h
> Remaining Estimate: 672h

> Hadoop/Pig are primarily used to parse log data, and most logs have a
> timestamp component. Therefore Pig should support dates as a primitive.
> Can someone familiar with adding types to pig comment on how hard this is?
> We're looking at doing this, rather than use UDFs. Is this a patch that
> would be accepted?
> This is a candidate project for Google summer of code 2012. More information
> about the program can be found at
