View how much time i spent on the Project

Steam works fine as a rough estimate.

I use an app/website called Timely which tracks how long you spend on each program on your computer.  Often it tells you which project or file you had open as well which is super helpful for timekeeping.  Unfortunately, this feature used to work for Adobe products but has stopped showing project info since CC2023.  Timely says this is something that Adobe needs to update, so they cannot do it.  It will still show you how long you worked on Premiere or After Effects etc.  And I believe it is smart enough to know when you have walked away from your computer with an app open.  It stops recording until you become active again.

You can post a feature request here, where the Adobe engineers read all threads:

yeah, but what happens if you leave premiere running while you go out to lunch?  Adding features to Premiere can cause problems... just follow this forum after an update is released.  There are all sorts of time management programs out there to keep track of your hours.  I just use Google calendar to enter my hours at the end of the day...  If you set up a new calendar, you can even share it with your clients so they have less excuse to scream when the see the hours  (usually doesn't stop them, but at least you've done due diligence).  

This would be useful

Timer, pencil and paper, my friend. 

No.

No.

Would find this useful myself.
