The Calculagraph is a device which mechanically calculates and prints the elapsed time between two events. Their best known, earliest use was as a means of tracking of table usage in pool halls . Later, until the advent of the digital era , they became the standard way to clock the duration of toll telephone calls.
where T is the tachymeter scale value; t is the time in seconds that it takes for the event to occur; and 3600 is the number of seconds in an hour. Showing 35 seconds elapsed, about 103 units by calculation. As a sample calculation, if it takes 35 seconds to travel one mile, then the average speed is 103 miles/hour. On the watch, 35 seconds ...
For stopwatches, the units of time that are generally used when observing a stopwatch are minutes, seconds, and 'one-hundredth of a second'. [5] Many mechanical stopwatches are of the 'decimal minute' type. These split one minute into 100 units of 0.6s each. This makes addition and subtraction of times easier than using regular seconds.
In computing, elapsed real time, real time, wall-clock time, wall time, or walltime is the actual time taken from the start of a computer program to the end. In other words, it is the difference between the time at which a task finishes and the time at which the task started.
Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity). When unspecified, "time dilation" usually refers to the effect due to velocity.
This process took a total of 0.02 seconds of CPU time (User + System). The reported System time is 0.00 seconds, indicating that the amount of System time used was less than the printed resolution of 0.01 seconds. Elapsed real time was 0.08 seconds. The following is the source code of the application nextPrimeNumber which was used in the above ...

The round-trip time or ping time is the time from the start of the transmission from the sending node until a response (for example an ACK packet or ping ICMP response) is received at the same node. It is affected by packet delivery time as well as the data processing delay , which depends on the load on the responding node.
