[GENERAL] does postgres log the create/refresh of a materialized view anywhere?

Is there a way to find out when a materialized view was created/refreshed?  I couldn't find this information anywhere
inthe docs. 

the use-case is that I wish to update a materialized view a few times a day in a clustered environment.  i'd like to
makesure one of the redundant nodes doesn't refresh if needed.  I can log this manually in postgresql if needed, but
washoping there was some "timestamp" on the view in a system table.
