Time based workflow not triggering

Time based workflow not triggering

Hi there,

I have a workflow setup on Potentials.  

It is set to activate on "Create or Edit" with NO Rule Criteria set (meaning I want it to fire on all records created or edited).


There are NO Instant Actions set.

There is ONE Time Based Action set.

Execution Time: 1 day after the Closing Date

Action: Update Fields (1): Field Update: Set Stage "Not in field".

However I just looked and saw that nothing has fired since I set this up.  The most recent should have fired on Jan. 18.

Am I required to setup a rule?  Or is your system just unreliable?  Or am I missing something.  I'd rather not waste my time depending on "Automation" if I always have to be double checking it is working as expected.
