Hi， rem queensthrone
Welcome to Microsoft Community.
According to your description, you transferred some files from your SD card to your PC.
There is no problem with the time setting of your PC.
Can you open the file and modify the file content normally now?
I think this may be a problem with the file system or SD card you used before:
Sometimes, the file system on the SD card may be wrong or damaged, resulting in incorrect timestamps. Check other files on the SD card for similar errors.
And if the system time on your PC or the device where the file was originally created was incorrect at some point, the wrong modification date may be set.
File transfer failure:
During the transfer process, especially in the event of interruption or error, the file properties may not be updated correctly.
Metadata problem:
The metadata of the file may have been changed or damaged, resulting in incorrect date information.
When modifying, please be sure to back up the original file to prevent file errors caused by unexpected problems.
To correct the modification date, you can use tools such as PowerShell or third-party applications. Here is a quick way to use PowerShell:
Open PowerShell as an administrator:
Right-click the Start menu and select Windows PowerShell (Administrator).
Run the command:
Use the following command to set the correct modification date:
(Get-Item "C:\path\to\your\file.txt").LastWriteTime = Get-Date "MM/DD/YYYY HH:MM:SS"
Replace "C:\path\to\your\file.txt" with the actual path to the file and "MM/DD/YYYY HH:MM:SS" with the correct date and time.
If you prefer graphical tools, you can use some third-party programs such as BulkFileChanger or Attribute Changer to easily modify file attributes.
