Timestamps Fiat 500e which format ? about fiatchamp HOT 7 CLOSED

Here's my HA-Code that works for me:

#Car timestamp

• platform: template
  sensors:
  wh_car_timestamp:
  value_template: >-
  {{ as_timestamp(as_datetime("1970-01-01 00:00:00.000000+01:00")+timedelta( milliseconds = states('sensor.car_timestamp')|int))|timestamp_custom('%d.%m.%Y %H:%M') }}

Offers me the timestamp on the surface like this: 13.03.23 09:15

looks like unix time in milliseconds. so its milliseconds elapsed since 1.1.1970 UTC. in home assistant it should be convertible with a template sensor or template card in the frontend. i don't know off the top of my head how exactly.

but does this timestamp mean anything important ? looks like a generic timestamp thats internally used by the fiat app to show last refresh time or something like that.

Thanks for the info wubbl0rz. I'll try and let you know.
As far as I wasn't able to decode the values in the past I have no clue what they could mean.
In fact there are three (different) timestamps:
car_evInfo_timestamp=1678431056968
car_timestamp=1678431056968
car_vehicleInfo_timestamp=1678430828730

You're right wubbl0rz. It's UTC+1 plus the value, which is in milliseconds.
The two different timestamps have a delta of around 3 minutes, no clue why and what that represents. Both values are around the time when the car was last connected via mobile.

nice good to know 😄 what is your use case with the timestamp or why do you want to see it ? does it give any meaningful information ?

Well, this timestamp seem to be the timestamp when all the data has been updated the last time. That's important for me, as my car is normally placed in my basement garage. The car uses mobile radio to communicate its data to the server. The car has a wifi module built in, though it doesn't use it to send its data. So, in my garage I have simply no connection. With the timestamp I see when the data has been fetched and so I have an idea, how good that (old) data is. I have extended my wifi to the garage but I have no mobile coverage. So, my pretty modern, new car is simply disconnected when I am at home and e.g. want to know how much energy is left before I start the charging process (because I like to charge not more than 80 %).
