Drupal 7 Tokens in Field Help text
Tokens in the "Help text" field work, at least for the taxonomy term reference field.

I tried adding "[current-date:long]&nbsp;[current-user:ip-address]" to the help text of a taxonomy reference field, and I obtained the following.



Tokens didn't work for the image field, though.

I have also tried with [current-date:custom:e], and it worked.



What confused me is that I didn't notice the summary of available tokens I normally expect from the Token module. It doesn't appear for the taxonomy reference field, but it appears for the image field, for which the tokens are not replaced.
