oik-clone v1.0.0-beta.0919 now supports storing of the cloned date.
It records the modified date of the version of the post when it was last cloned to a particular server.
This information will be invaluable in future versions which will determine what needs to be cloned after you’ve done a number of updates.
Note: Since this plugin is still a beta version there is no backward compatibility. Servers need to be updated to the latest version.
