Adam Szita commented on PIG-4748:
---------------------------------
[~rohini] I think this behaviour is consistent with what we have in trunk now:
{code}
grunt> cat fruits.csv
apple 1 red 1971-01-01T00:00:00.000+00:00
orange 2 orange 1972-01-01T00:00:00.000+00:00
kiwi 3 green 1973-01-01T00:00:00.000+01:00
orange 4 orange 1974-01-01T00:00:00.000
grunt> A = LOAD 'fruits.csv' as (name:chararray, id:int, fruit:chararray,
fut:datetime);
grunt> dump A;
(apple,1,red,1971-01-01T00:00:00.000Z)
(orange,2,orange,1972-01-01T00:00:00.000Z)
(kiwi,3,green,1973-01-01T00:00:00.000+01:00)
(orange,4,orange,1974-01-01T00:00:00.000+01:00)
{code}
(On my US-based cluster I get (-07:00) for the last record using the same data
and query)

> The following test fails:

> @Test
> public void foo() throws IOException {
> DateTime nowIn = DateTime.now();
> DateTimeWritable in = new DateTimeWritable(nowIn);
> ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
> DataOutputStream dataOut = new DataOutputStream(outputStream);

> dataOut.flush();
> // read from byte[]
> DateTimeWritable out = new DateTimeWritable();

> DataInputStream dataIn = new DataInputStream(inputStream);
> out.readFields(dataIn);
> assertEquals(in.get(), out.get());
