I want to know the answer to the following question:
Along with :45, :30 and :15 past the hour, at what time do TCM features begin?
All the background I'm provided with is that "In addition to this, extended breaks between features are filled with theatrically released movie trailers and classic short subjects – from series such as The Passing Parade, Crime Does Not Pay, Pete Smith Specialties, and Robert Benchley – under the banner name TCM Extras (formerly One Reel Wonders).". Is that enough to answer the question?
Answer: no
