Jiffy values for various Linux versions and platforms have typically varied between about 1 ms and 10 ms, with 10 ms (1/100 s) reported as an increasingly common standard in the Jargon File. [ 11 ] Stratus VOS (Virtual Operating System) uses a jiffy of 1/65,536 second to express date and time (number of jiffies elapsed since 1 January 1980 00: ...
The construction of economic time series involves the estimation of some components for some dates by interpolation between values ("benchmarks") for earlier and later dates. Interpolation is estimation of an unknown quantity between two known quantities (historical data), or drawing conclusions about missing information from the available ...
