I saw this post on the Movable Type forums, and thought that it might be an interesting little plugin that could be valuable for academic environments. In a nutshell, Timestamp Guard prevents people who lack the administrative permissions from changing the timestamp on a post or entry.

I tested it locally on my MacBook Pro and on a test environment I have hosted on my blog, and it worked in both places with unprivileged users. If anyone has any problems, please let me know what's going on with a comment that describes in detail what was done and what was going wrong.

If you like this work, please consider rattling the ol' tip jar!
