Café del tiempo is a regular coffee or coffee with milk or in this case a cortado ( strong coffee with a bit of milk) mixed with ice cubes.
In Valencia this is very popular in summer and you can order it in every bar. You just have to say the coffee you want and add the words “del Tiempo” and you get a glass with ice with your coffee. Somtimes you get a slice of lemon with it.
