Description

I've run:
[root@localhost Downloads]# java -jar tika-app-2.9.0.jar sobreavisoEditado3.pdf | grep xmp

that returned a time in UTC

WARN [main] 07:42:34,238 org.apache.pdfbox.pdmodel.font.PDType1Font Using fallback font LiberationSans for base font Symbol
WARN [main] 07:42:34,241 org.apache.pdfbox.pdmodel.font.PDType1Font Using fallback font LiberationSans for base font ZapfDingbats
<meta name="xmp:ModifyDate" content="2023-09-06T13:35:38Z"/>
<meta name="xmp:MetadataDate" content="2023-09-06T13:35:38Z"/>
<meta name="xmpTPg:NPages" content="11"/>

 

 

While running:

 {{java -jar pdfbox-app-2.0.29.jar ExtractXMP -console sobreavisoEditado3.pdf }}

Returned the correct info with the timezone info (-04:00):

<?xpacket begin="" id="W5M0MpCehiHzreSzNTczkc9d"?><x:xmpmeta xmlns:x="adobe:ns:meta/"><rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"><rdf:Description rdf:about="" xmp:ModifyDate="2023-09-06T13:35:38-04:00" xmlns:xmp="http://ns.adobe.com/xap/1.0/"><xmp:MetadataDate>2023-09-06T13:35:38-04:00</xmp:MetadataDate></rdf:Description></rdf:RDF></x:xmpmeta><?xpacket end="w"?>{}

 

So the metadata string had striped its timezone info, without making any HOUR OF DAY shift to the UTC timezone.
