Standard atomic clocks in use today, based on the atom cesium, tell time by counting radio frequencies.
Pfeifer also envisages x-ray atomic clocks which are far more precise than even the most advanced optical atomic clocks nowadays based on visible light.

Dozens of GPS satellites, all containing extremely accurate atomic clocks, have been launched since the late 70's, and launches continue to this day.
Today, caesium atomic clocks are the basis for official standardized universal time and lose only one second every 30 million years.
The international world time is calculated from the average number of more than 200 synchronized atomic clocks.
Achieving the necessary level of isolation in practice means that the best atomic clocks take up entire rooms.
