172:(limiting the timing resolution to .016 seconds). Many modern systems, such as those manufactured by FlashTiming, are capable of frame rates of 120 frames per second at higher spatial resolution and in a purely digital regime. The addition of computer based analysis tools has greatly simplified and made efficient the process of timing races, as well as automated some portions of timing labor such with features such as motion detection and bookmarking of finish times. Owing to these developments and the lower cost compared with line-scan systems, video timing has seen some limited level of adoption at a few high-school and collegiate events. The inability of these systems to perform what is known as a "zero control test" means that they do not comply with the requirements of the IAAF or other national governing bodies to be classified as fully automatic timing (FAT).

overall system was similar to that used in London in 1948 (the Racend Omega Timer). The average difference between the FAT and manual times for the men's 100 meters was 0.24 seconds, although this ranged from 0.05 seconds to 0.45 seconds; for example, the average difference for the six runners in the men's 100 meter final was 0.41 seconds; while the average difference in the women's 100 meters was also 0.24, but only 0.22 in the final. In the men's 200 meters, the average difference was 0.21 seconds, and in the men's 400 meters the average difference was 0.16 seconds.

many applications outside of athletics). These systems provide instant results which can be very beneficial when there is a large group of athletes (such as a combine) or if coaches are wanting to quickly time their athletes. This type of FAT technology is used widely in the world of sports performance and movement research and can be much more affordable and easy to use when compared to the camera based systems. Break-beam timing systems have manufacturers worldwide including:

335:. Accutrack was the most popular photo-finish camera in the United States in the late 1980s and into the early 1990s, but there were some limitations to the film based cameras (the film was advanced on a carriage that would sometimes jam, the width of film limited the amount of data—and thus times that could be captured, etc.) and this led to occasional failures during use.

systems in 1964 and 1968 had a built-in 0.05 second delay, meaning Hayes' FAT time was measured as 10.01 seconds, which was rounded to 10.0 seconds for official purposes (despite the fact that officials with stopwatches had timed Hayes at 9.9 seconds). The currently understood time of 10.06 has been determined by adding the 0.05 seconds delay back in.

continued to use Omega timing with a device called the 'Magic Eye', developed by
British Race Finish Recording Co. Ltd. The automatic times produced in the 1948 Olympics have never been released, but examination of the photos at the finish means that margins have been calculated to 1/100 second accuracy.

In the case of comparing an adjusted manual time to FAT timing with an original FAT time being equivalent, the FAT time will be considered more accurate, and thus the athlete will be given the higher seed, or comparison ranking. This method of converting times dates back to when FAT systems were much

In 1952 the Omega Time

There are also similar timing systems that use the process of breaking a beam of light. Such systems are frequently used when athletes are tested individually. The nature of this technology does not recognize who is breaking the beam, but instead when the beam was broken (allowing it to be used in

In 1964, although manual timing was also used at the
Olympics, the official times were measured with a FAT system but were given the appearance of hand times. For example, Bob Hayes won the 100 meters in a FAT time of 10.06 seconds, which was converted to an official time of 10.0 seconds: the FAT

It was used extensively in North
America, including at the 1948 US Olympic trials. The Bulova device was activated by the sound of the starting gun firing, rather than by a direct connection, which means that the times were around 0.02 seconds faster than reality. The 1948 Olympics, however,

FAT was also used in 1936, but very few times have been found. In 1948, Bulova began developing the
Phototimer, a unique combination of photo-finish camera and precision electronic timing instrument. The Phototimer was the first automatic timing device to be used in competitive sports.

In 1960 the average difference between the FAT and manual times for the men's 100 meters was 0.15 seconds, ranging from -0.05 to 0.26 seconds. In the men's 200 meters, the average difference was 0.13 seconds, and in the men's 400 meters the average difference was 0.14 seconds.
312:
In 1956 the average difference between the FAT and manual times for the men's 100 meters was 0.19 seconds, ranging from -0.05 to 0.34 seconds. In the men's 200 meters, the average difference was 0.16 seconds, and in the men's 400 meters the average difference was 0.11 seconds.

In 1972, having provided the official timing equipment since 1932, Omega lost the right to be the official timer for the
Olympics to Longines. Omega returned for the 1976 Olympics. This was the first Olympics where official results were given to the nearest 1/100 seconds.

Hand times, i.e. those with humans operating the stopping and/or starting mechanisms, are highly prone to error. By rule, they are only accurate to a tenth (.1) of a second, so all 100ths of a second beyond zero must be rounded to the next highest tenth.
