Yes! By default, LinkFixer Advanced will maintain the last modified date and time of files that it processes. If you wish to disable this option, you can do so by selecting “Options | Files | Processing Options” dialog and disabling the “Maintain original file modified dates and times” checkbox for the Classic UI and going to the "Hamburger menu | Settings | Files | Timestamps" dialog and disabling the “Maintain original file modified dates and times” for the New UI.
