Attribute Changer is the right tool to modify image EXIF information by manually entering date and time values. Or you can choose to synchronize info with time stamps and file date.
Several other functions enable users modify the background data on a photo. And if one wishes to keep date and time stamps the way they were before copying a folder or a file from one place to another, then this tool has the answer for the problem.
Randomly generated time stamps may also apply. Attributes to files and folders can also be modified in terms of security: make read only files, create backup files. And the greatest thing about this software is that it integrates nicely into shell, so a single right click spares you this problem.
