Nope. The built in UI of the Leaf provides nothing to the user to know when charging has completed/how long it took. However, if you have a Leaf SV or above, you can turn on notifications so that you get Carwings emails/texts when charging is complete.
Leaf S models (w/o nav systems and thus w/o telematics and cellular radio) are out of luck w/the above.
If the EVSE you use is networked, it might have stats, just like networked ones from Chargepoint do. If you have a smart meter at home and your electric provider gives you some means of viewing consumption on an hourly (or finer grain) basis, you could figure out roughly when your car stopped charging.
