Abstract

A time-measuring device having a quartz oscillator (4) as time standard contains, inter alia, two logic circuits (5, 6), one logic circuit (6) receiving signals independent from one another in parallel and relaying the information contained therein as a time-division multiplex signal. The invention is used, in particular, for quicker detection of very slight time deviations. <IMAGE>
