Can I copy the field Time Tracking?

[ruslans.klimovs]

Hello! 

I have a project where we use the field "Time Tracking" actively.

Is it possible to create an additional custom field "Time Invoiced" which will look like "Time Tracking"?

To the best of my understanding Time Tracking isn’t a single field but rather a culmination of original estimate, time logged and time remaining. So to copy these you would create three custom fields and use some method of copying, e.g. post function, automation or scripting.

Yes, that's right.  In a purely technical sense, Time Tracking is a "field", as far as it's "a single object that goes on a screen", but the code behind it is not simple, either on how it is calculated, stored or rendered.  And it's just a field, it is not a field type.  So you can't have more than one of it.
