find device registration date

Hi All!

how can I find device and user registration date?
the /api/device does not have a such information

Traccar doesn't have that information by default. I added it by modifying the code and adding a new column in tc_devices and tc_users.

You should be able to find it in logs, but not the database or API.

I think, it is good idea to have them on the database

I did something similar, but I included it as an attribute so I wouldn't have to create additional columns and be able to work with the updates without converting the database,

carlock please how did you create this attribute, what parameter did you use?
