What is sensor.date_time_2?

Configuration
1

I added the date and time integration so I could have a clock on my main dashboard. Everything is fine, except the integration has 4 entities: date, time, date_time, and date_time_2. Only date_time can be managed in the gui, the others report “no unique ID” when I try.

What is sensor.date_time_2 and how can I get rid of it? Is there any way to tell if anything uses it?

Thanks

My guess is date, time and date_time_2 are from the date and time integration, as these are not manageble from the gui, and your date_time comes from another integration.

Easy to check from settings → devices & services → entities
