The utility function homeassistant.util.dt.utc_to_timestamp is deprecated and will be removed in Home Assistant Core 2026.1, custom integrations which call it should instead call the stdlib method datetime.datetime.timestamp()

The reason for deprecation is that the stdlib method is just as fast as the utility function.

More details can be found in the core PR.
