I have an important court document that is showing a modification to the internal meta data(Im suspecting fraud). The program used to modify the file is: tx11 pdfversion 11.0.111.501
Is there any program that can roll the file back to the original?

What application is putting the message out, what function is doing the test, and what is the exact wording?

   They emailed me the file, I am on xp, right click properties there is a separate pdf tab. Indicating: The file was created jan 2012 and modified August 2013. The pdf producer is tx11 pdf 11.0.111.501.
   I had a friend of a friend look at it and he said "the content was modified, not the file container itself, August 1st 2013, 5:13 a.m. according to its meta data the modification was made by tx11 pdf version 11.0.111.501". He gave me a printout of the metadata but I dont know the program used.
   Whats interesting is the
modification date is the same in pdf properties tab but the modification time is 9 am a 4 hour difference. 5 am is before office hours 9 am is shortly after arriving. The august date was a week after a court order.

Many time strings are based on the UTC date and time and then displayed to the user as the local time or the UTC adjusted for the time zone offset for the local time zone.
Is there a time zone difference involved?

I believe you are correct because the minutes are the same; but the modification occurred 19 months after the document was created.
