A recorded female voice says: "Es wird mit dem Summerton 15 Uhr, 53 Minuten und 10 Sekunden", meaning "At the buzzing tone, the time will be 15 hours, 53 minutes and 10 seconds", followed by a short pause and a 1 kHz, 0.25 seconds long beep (even though the announcement "buzzing tone" suggests otherwise).
[9] [failed verification] Each degree was subdivided into 60 minutes and each minute into 60 seconds. [10] [11] Thus, one Babylonian degree was equal to four minutes in modern terminology, one Babylonian minute to four modern seconds, and one Babylonian second to 1 / 15 (approximately 0.067) of a modern second.
To help compare orders of magnitude of different times, this page lists times between 10 −3 seconds and 10 0 seconds (1 millisecond and one second).
Finland – On YLE's radio services the pips are broadcast on the hour. [24] Hong Kong – A six-pip time signal is used on RTHK's radio channels.

Now suppose the store is considering doing more advertising to raise the arrival rate to 20 per hour. The store must either be prepared to host an average of 10 occupants or must reduce the time each customer spends in the store to 0.25 hour.

Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars . Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation.
Air changes per hour, abbreviated ACPH or ACH, or air change rate is the number of times that the total air volume in a room or space is completely removed and replaced in an hour. If the air in the space is either uniform or perfectly mixed, air changes per hour is a measure of how many times the air within a defined space is replaced each hour.
Some authorities regard two seconds as inadequate, and recommend a three-second rule. [4] German law requires a minimum 0.9 second distance but when tested under relaxed conditions [5] researchers found that their test subjects spent 41% of the test time at following distances under 0.9 seconds.
