Abstract:
Fluctuations of "computer time" provided by the PC quartz generator were studied. It was shown that variations in the yearly course of the quartz generator frequency occur with periodicities of 13-15 days and 28-30 days. Regular fluctuations with periods of 0.5 and 1.0 min are typical of the short-term spectral component. Impulses of sharp and intense deceleration of "computer time" are often observed against the background of these regular fluctuations. The conclusion is made that fluctuations of "computer time" are of cosmophysical origin.
