Me too, so this is either not working since a long time (or since initial implementation?), or both of us are equally dumb to not understand how to properly use it.

Any news from your side? At least to me it looks like it's expecting an argument and bailing out after not finding one. Would be great to join for this research.

Replying to hasienda:

Sadly it turned out to be option 2 - too dumb to follow the docs. In fact, if you strictly follow the documented syntax, it works instantly.

Remember, that a operation:argument syntax is expected. The problem arises, because this is non-intuitive for this operations. Anyway, following code has been tested successfully:

[tf.form_updater:] [tf.form_updated_on:%c]

Note: The strftime format string is optional, while the colon is not!

I'll close this issue after adding the aforementioned example in the documentation for extra clarity.
