Describe the issue

I just noticed that all 4 of the tire pressure last measured sensors ( such as sensor.carname_tire_pressure_last_measured_front_left ) are given one hour later than reality, putting the value into the future.

I verified my timezone (UTC -7) is correct in HA settings, and {{ now() }} in developer template gives the correct local time. But the tire pressure measured values were given one hour later than actual.

Super minor bug, but let me know what troubleshooting or logs you need to investigate. Thanks.

Reproduction steps

1. Take a drive, so that the car updates the tire pressures
2. Note the value of "sensor.carname_tire_pressure_last_measured__" are all one hour later than reality
3. Have a cold one

I don't think I can fix this, the timestamps come from your vehicle. Are you sure the timezone in your Home Assistant integration is correct?

You might need to create a separate user/password for your car to specify its timezone. Is your energy dashboard shown correctly on the vehicle's web browser (do you use Home Assistant from the car's browser?)?

Are you sure the timezone in your Home Assistant integration is correct?

From OP: "I verified my timezone (UTC -7) is correct in HA settings, and {{ now() }} in developer template gives the correct local time. " If there is some other method that you want me to check, let me know

on the vehicle's web browser

I view Home Assistant through the Android app, or a desktop browser, but not the car's browser. Car's clock has the correct local time displayed on the screen.

Okay, so I watched the SSE display as someone else drove the car.

I see the field "tpms_last_seen_pressure_time_fl":1737388273 . This timestamp is
"Unix Epoch 1737388273 Time
(UTC) Mon Jan 20 15:51:13 2025 UTC Time
(America/Denver) Mon Jan 20 08:51:13 2025 MST" according to DuckDuckGo.

However, the Home Assistant display for this field is showing 09:51 local.

All other timestamps and datetime strings in the SSE appear to be correct to UTC.

So the car is reporting the time of the event correctly. Somewhere in HA or the Teslemetry integration, an extra hour is being tacked on somewhere. I checked a random sampling of other Teslemetry integration created entities, all report last update as "X seconds ago", data is correctly in the past, etc. It appears to only be the TPMS last report entities that are affected AFAICT.

EDIT: fixed bad copy/paste of Unix timestamp after "I see the field...."
