Solr not preserving milliseconds precision for zero milliseconds

[Pratik Patel]

Hello Everyone,

Say I have a document like one below.


> {
>         "id":"test",
>         "startTime":"2013-02-10T18:36:07.000Z"
> }


I add this document to solr index using the admin UI and "update" request
handler. It gets added successfully but when I retrieve this document back
using "id" I get following.


 {
>         "id":"test",
>         "startTime":"2013-02-10T18:36:07Z",
>         "_version_":1580456021738913792}]
>   }


As you can see, the milliseconds precision in date field "startTime" is
lost. Precision is preserved for non-zero milliseconds but it's being lost
for zero values. The field type of "startTime" field is as follows.

<fieldType name="date" class="solr.TrieDateField" positionIncrementGap="0"
> docValues="true" precisionStep="0"/>


Does anyone know how I can preserve milliseconds even if its zero? Or is it
not possible at all?

Thanks,
Pratik
