Comment 10 for bug 819995

I have tried some solutions before i found this bug,

An extract of metadata made with exiftool (libimage-exiftool-perl 9.46-1) shows an important difference on a document that displaying dates right, and one sample print-to-file, the tags for PDF related date info is totally missing:

-PDF:CreateDate=
-PDF:ModifyDate=

Example command:
exiftool -args -G1 --filename --directory PDF_FILE_NAME.PDF

Example output of Print-to-File:
-ExifTool:ExifToolVersion=9.46
-System:FileSize=107 kB
-System:FileModifyDate=2018:02:22 00:56:18+01:00
-System:FileAccessDate=2018:02:22 00:56:40+01:00
-System:FileInodeChangeDate=2018:02:22 01:30:18+01:00
-System:FilePermissions=rw-rw-r--
-File:FileType=PDF
-File:MIMEType=application/pdf
-PDF:PDFVersion=1.5
-PDF:Linearized=No
-PDF:PageCount=1
-PDF:Creator=cairo 1.13.1 (http://cairographics.org)
-PDF:Producer=cairo 1.13.1 (http://cairographics.org)

Example output of PDF with working dates:
-ExifTool:ExifToolVersion=9.46
-System:FileSize=3.2 MB
-System:FileModifyDate=2015:11:02 14:37:59+01:00
