Remove exif data without altering the modified date and time?

[imajica]

I want to be able to remove all metadata from a file.... so this is what I am doing:

exiftool.exe -overwrite_original -all= filename.jpg

This works... except that it changes the modified date to the current date and time.  Is there a way to remove the data, but leave the modified date and time alone?

Thanks,

Use the -P (-preserve) option.
