  }
  });

Context

I need to change the timestamp format used in the location template.
I tried adding an extra param but the value is computed when the config is called and it's not updated at each location update.

Expected Behavior

I would expect that the values in the extras parameter are recalculated at each update.

Actual Behavior

Extras are generated when the config method is called and are not updated.

Is there a way to send the timestamp in a different format?
I need to send the timestamp in epoch format, like 1645455040.

You can't.

You have to convert the timestamp as desired at your server.
