exiftool.exe -TAG

Extract information for the specified tag (eg. -CreateDate).
Multiple tags may be specified in a single command.
A tag name may include leading group names separated by colons (eg. -EXIF:CreateDate,

D:\rive\Temp>exiftool.exe -CreateDate "TEST.pdf"
Create Date : 2011:02:09 12:49:02+01:00

D:\rive\Temp>

exiftool.exe -d FMT (-dateFormat) Set format for date/time values

D:\rive\Temp>exiftool.exe -d "%Y-%m-%d" -CreateDate "TEST.pdf"
Create Date : 2011-02-09

D:\rive\Temp>exiftool.exe -d "%Y-%m-%d %H%M%S" -CreateDate "TEST.pdf"

Working code to get the CreationDate (no matter if German or English format):

by using exiftool.exe -d "%Y-%m-%d %H%M%S" -CreateDate "TEST.pdf"

Instead of Xpdf-pdfinfo.exe

(((output here in German date format, missing leading zero on date less then 10, month name as name/word.
Needs additional treatment for an useful output)))

Tip from den4b "-rawdates", that will simplify the scripts above.

pdfinfo.exe -rawdates

So we can use one tool for both EXIF and PDF? ... more test needed...

# # #

More tested:

To insert Date Taken of an Image/Picture,
you can use the [Insert Meta Tag]-button
to insert meta data /TAGs from files, like ":EXIF_Date:".

Example:
1) Insert: Insert "_" as Prefix (skip extension)
2) Insert: Insert ":EXIF_Date:" as Prefix (skip extension)
Example output: 2006-07-07 20-12-17_OldName.JPG
Use further rules to modify that output to an format you want to use for your NewName.

Also you can utilize command line tools like exiv2.exe or exiftool.exe
together with an PascalScript to perform all need modification in one single rule.

Based on Script by Author: Denis Kozlov. Date: 2013-04-01. ( http://www.den4b.com/wiki/ReNamer:Scripts:Exiv2 )

exiv2.exe
https://www.exiv2.org/download.html

const
  EXE = 'exiv2.exe';
  //https://www.exiv2.org/download.html
  //EXEMPLE COMMANDLINE OUTPUT: Image timestamp : 2006:07:07 20:12:17
  TAG = 'Image timestamp\s*\:\s*(.*?) (.*?)[\r\n]';

var
  Command, Output: String;
  Matches: TWideStringArray;

begin
  Command := EXE+' "'+FilePath+'"';
  if ExecConsoleApp(Command, Output) = 0 then
  begin
    Matches := SubMatchesRegEx(Output, TAG, False);
    if Length(Matches) > 0 then
    begin
      //showmessage(Matches[0]); // 2006:07:07 20:12:17
      Matches[0] := WideReplaceStr(Matches[0] ,':','-');
      Matches[1] := WideReplaceStr(Matches[1] ,':','');

      // Compose   wanted   new name:
      //FileName := Matches[0] +'_'+Matches[1]+ WideExtractFileExt(FileName);
      FileName := WideExtractBaseName(FileName)+'_('+Matches[0]+'_'+Matches[1]+')'+WideExtractFileExt(FileName);
    end
    else
      FileName := '__NOTHING_FOUND__' + FileName;
  end;
end.

Here with more comments for self learning:

exiftool.exe

  EXE = 'exiftool.exe';
  //https://sno.phy.queensu.ca/~phil/exiftool/
  //EXEMPLE COMMANDLINEOUTPUT: Create Date                     : 2006:07:07 20:12:17
  //RegularExpression for the SubMatchesRegEx() command below:
  TAG = 'Create Date\s*:\s*(.*?) (.*?)[\r\n]';

var
  Command, Output: String;
  Matches: TWideStringArray;

begin
  //Build the command line command and store in var "Command":
  Command := EXE+' "'+FilePath+'"';
  //Execute the Command and gather result in var "Output":
  if ExecConsoleApp(Command, Output) = 0 then
  begin
    //Execute SubMatchesRegEx() on var "Output"
    // with expression in var "TAG"
    //   to get the wanted line from "Output":
    Matches := SubMatchesRegEx(Output, TAG, False);
    //If something is found "Matches == 1 or more":
    if Length(Matches) > 0 then
    begin
      //showmessage(Matches[0]);   //Shows for example "2006:07:07 20:12:17"
      Matches[0] := WideReplaceStr(Matches[0] ,':','-');
      Matches[1] := WideReplaceStr(Matches[1] ,':','');

      // Compose  wanted   new name:
      //FileName := Matches[0] +'_'+Matches[1]+ WideExtractFileExt(FileName);
      FileName := WideExtractBaseName(FileName)+'_('+Matches[0]+'_'+Matches[1]+')'+WideExtractFileExt(FileName);
    end
    else
      FileName := '__NOTHING_FOUND__' + FileName;
  end;
end.
