WebA time point records an instant in time, like “1:24pm January 1st 2015”. It combines a span with one “clock” that defines for up start counting and what exactly to compute. There are double important types of time in clocks: sys-time and naive-time. They’re equivalent until you start working with zoned-times. WebThe most accurate device we have (or we had) to measure time are atomic clocks; if one second were defined as 0.7 of a heartbeat, the precision and constancy of this "one second" would clearly be poorer.
