For most of us, a second is perhaps the finest level of granularity when it comes to measuring time! And why it shouldn't be? Even the most precise Olympic stopwatches measure the fractional levels of second to a fraction of three decimals. Any real world application hardly requires time to be measured at a finer level of granularity. Well, this may be the scenario at present but certainly not likely to remain the fact in near future. The Digital Time concept by Freddie Yauner measures time to the precision that takes the unit of a second at highly coarse level - several times coarser than the present ratio of an hour and a second! The Digital Time takes the finest level of granularity to the level of atomic time - down to the millionth fraction of a second! Wonder what applications it's going to be used in? Well, efforts never go in vain, neither do measurements! Just take a look at the video to have an idea.
