Konstantin Gribov commented on TIKA-3493:
-----------------------------------------
Just hit the same with one of the tests failing. I looked through RTF spec 1.9
and they effectively have local date/time (just wallclock without time zone)
there.
Right now it's interpreted as date/time in current jvm timezone. Both
LibreOffice and Word (on Mac) interpret them the same.
Maybe we should keep it without timezone in the metadata string (in
{{dcterms:created}} or another property) and only reinterpret it with a TZ in
{{Metadata#getDate}} but it would be a breaking change. Or if we can keep raw
representation plus Tika's best guess what instant it meant. Likely to require
breaking changes too.

> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 2.0.0
> Reporter: David Pilato
> Assignee: Tim Allison
> Priority: Minor

> {color:#333333}I'm migrating an existing project to Tika 2.0.0.
> I'm seeing a strange behavior.
> TL;DR: the created date of the document changes depending on the timezone.
> Long story:
> I have a unit test which extracts content and metadata from a [RTF
> document|[https://github.com/dadoonet/fscrawler/raw/master/test-documents/src/main/resources/documents/test.rtf]].
> When using Tika 1.27, whatever the timezone defined for my JVM, I'm always
> getting the same value for "dcterms:created": "2016-07-07T13:38:00Z".
> When running the same test with Tika 2.0.0, the date changes depending on the
> Timezone.
> For example:
> {color}
> * {color:#333333}Asia/Sakhalin gives dcterms:created=2016-07-06T23:38:00Z
> {color}
> * {color:#333333}Asia/Colombo gives dcterms:created=2016-07-07T05:08:00Z
> {color}
> * {color:#333333}Europe/Stockholm gives dcterms:created=2016-07-07T08:38:00Z
> {color}
>
> {color:#333333}I don't know if it's a bug or expected. May be the RTF format
> does not specify the Timezone.
> I'm surprised that I don't see the same behavior for Office documents
> actually.
