Eugenio Panadero d5e606640c Fix scheduled update time-drift in data update coordinator (#32974)
* Fix scheduled update time-drift in data update coordinator

As next schedule is calculated **after** the update is done,
setting now + update_interval makes 1 second drift in practice,
as the tick is 1Hz.

* Floor the utcnow timestamp

to remove sub-second error precision, and generate constant frequency updates
as long as the update takes < 1s.
