Photoshop Feature request: time management

We need a feature that very clearly tells you how much time you've put into a file. I've seen some competitor creation programs that have this feature and they are extremely easy to access. 

Every time I try to figure out how to do this on photoshop, I'll get instructions to go into the file info and search there (this never works, and apparently you have to do it at the start of each file?) or I've also seen people install third-party apps to track this which is crazy to me since adobe is usually so great
