>                 Key: DAFFODIL-2017
>                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2017
>             Project: Daffodil
>          Issue Type: Bug
>          Components: Back End, Compatibility
>    Affects Versions: 2.2.0
>            Reporter: Michael Beckerle

> Ran under IBM DFDL. The test failed.
> Differences are 
> * IBM uses "Z" where Daffodil uses "+00:00"
> * IBM shows "000" for fractional seconds where Daffodil does not
> Question is: which one is correct and why. If "both" behaviors are "allowed", 
> then we likely need a switch in Daffodil to prefer the same behavior as IBM 
> DFDL, vs. staying with the current behavior (which we still need to preserve 
> for existing users.)
> Here's the output when running on IBM DFDL.
> {{org.apache.daffodil.tdml.TDMLExceptionImpl: (Implementation: ibm) 
> Comparison failed.

> Differences were (path, expected, actual):
>  (calendar_group/date1,'2010-12-30+00:00','2010-12-30Z')
> (calendar_group/time1,'04:05:06+01:00','04:05:06.000+01:00')
> (calendar_group/datetime1,'2010-12-30T04:05:06+00:00','2010-12-30T04:05:06.000Z')}}
> The same issues arise for these tests:
> test_simple_type_properties_text_calendar_13_03
> test_simple_type_properties_text_calendar_13_04
> test_simple_type_properties_bin_calendar_13_01
> test_simple_type_properties_bin_calendar_13_02
> test_length_delimited_12_01
> test_length_delimited_12_02
>       
> These tests originated with IBM (a LONG time ago), though it's possible we 
> changed them to match Daffodil behavior if we thought the behavior was 
> correct the way we changed it.
