lgtm.
Do we want to fix PST while we're at it? Or separate PR?
From my claude:
```
PSTMailItemParser.java (a separate parser for .pst archives) has the same
pattern:
metadata.set(TikaCoreProperties.MODIFIED,
pstMail.getLastModificationTime());
If pstMail.getLastModificationTime() has the same storage-level semantics
as PR_LAST_MODIFICATION_TIME, PST mail
items could exhibit the identical bug.

> We use Tika to extract metadata from msg files. We found out that the value
> of metadata dcterms:modified with Tika 3.2.3 is different from that with Tika
> 2.9.0 for some msg files.
> Following is the stand alone program that reproduces the problem with the
> attached sample files. The Java version is 21.
