How should I address the concept of time with a client?

[Bearofdistinction]

I have two playlists that I like to start playing when a provider arrives. One lasts just under 1 hour, and the other is an hour forty-five. Depending on how long I've booked, I'll tell Alexa to play the appropriate playlist so I know that when the music stops, time's just about over. Time to wind things up.
