How to Fix PDF Showing Wrong Date Stamp After Saving
Question details
The user needs to correct a PDF file that displays an inaccurate creation or modification date after being moved or renamed.
- Product
- Device & OS
- Windows 7, Windows XP
- Scenario
- Renaming and saving a PDF file to a new location or transferring it between older and newer Windows operating systems.
- Observed behavior
- The file properties incorrectly display a date stamp of December 31, 1999, instead of the actual creation or modification date.
Before troubleshooting, verify whether the incorrect date appears inside the PDF document text itself or only in the Windows file properties, as these require different fixes.
Check and Update File System Properties
File system transfers between older OS versions can sometimes corrupt metadata. Verifying and updating the file properties can help identify and resolve the issue.
When transferring files from legacy systems like Windows XP to Windows 7 or newer, older metadata formatting can be misinterpreted by the newer OS, resulting in default fallback dates like December 31, 1999.
Right-click the affected PDF file in Windows File Explorer and select 'Properties' from the context menu.
Navigate to the 'Details' tab to review the 'Date created' and 'Date modified' fields to see if the metadata is corrupted.
To force the operating system to apply a new timestamp, open the PDF in your default viewer, select 'Save As', and save a fresh copy to a completely different folder.
Re-export the PDF from the Original Source Document
If the PDF metadata is permanently corrupted, generating a fresh PDF from the original Word document will apply the correct current timestamps.
Edit and Export PDFs with Correct Metadata in WPS Office
Avoid legacy timestamp bugs by using WPS Office to create, edit, and save your PDF documents. WPS provides seamless PDF conversion and proper metadata handling, ensuring your file properties are always accurate.
- 1. Open your document: Launch WPS Office and open the original Word document or the affected PDF file.
- 2. Edit document information: If necessary, modify the contents or update the text indicating the date directly within the PDF document.
- 3. Export to a fresh PDF: Click 'Menu' > 'Export to PDF' to generate a brand new file, which will automatically receive the correct, up-to-date system timestamp.
Frequently Asked Questions
Why does my PDF show a date from 1999?
This is often related to a legacy system glitch where file transfers between older operating systems (like Windows XP) and newer ones fail to parse the timestamp metadata correctly, defaulting to a date like December 31, 1999.
Is the incorrect date part of the PDF content?
Usually, no. The date shown in the file explorer is part of the file system's metadata (properties), not the actual text printed inside the pages of the PDF document.
Can I manually change the creation date of a PDF?
Yes, you can change file metadata using third-party file attribute changer software, or by simply duplicating the file using 'Save As', which usually resets the 'Date Created' stamp to the current day.
Will emailing the file fix the date stamp?
Sometimes. Downloading an emailed file creates a brand new file on your hard drive, which will update the 'Date Created' to the moment it was downloaded, though 'Date Modified' might still retain the old corrupted metadata.
