Set this check box to preserve the file modification time when the version is added to source control, checked in, or checked out.
Clear this check box to reset the file modification time. If the file is being added to source control or checked in, the modification time is reset to the checkin time. If the file is being checked out, the modification time is reset to the checkout time.
