I have a timestamp in a mysql table with attribute "ON UPDATE CURRENT_TIMESTAMP". Is there a way to manually disable updating the timestamp on a special occasion? (eg: updating the entry to revise a blog post, but not to re-date it)

Sounds like you need to configure the default constraint so that it populates the column on insertion only:
DEFAULT CURRENT_TIMESTAMP
Changing it to only be this means that any revisions will not trigger the timestamp value to be updated. IE: If you created the blogpost yesterday, and corrected a typo today - the date in the column would still be for yesterday.
