title: Digital versus conventional clocks - a review.
abstract: This article reviews two scientific papers by van Nes and Zeff, describing comparisons between digital and analogue (conventional) time displays. The first part deals with an investigation of speed and accuracy in reading small time differences. It was found that a small time difference can be determined more quickly and precisely from simultaneously presented displays, if the displays are digital. The second part describes an experiment devised to compare the two modes of time display with respect to the speed and accuracy of reading and logging. It was shown that it takes [Formula: see text] to 4 times longer to read (and 10 times more errors are incurred) from a conventional (analogue) time display than from a digital one.
