Abstract
THE Colaba Observatory has had under regular observations the time-signals broadcasted from Eiffel Tower and Nauen. A good deal of confusion was sometimes caused when the Observatory clock, which showed almost perfect agreement with the ordinary signals (old system) transmitted from Eiffel Tower between 22 hr. 44 min., and 22 hr. 49 min. G.M.T., received here between 4 hrs. 14 min. and 4 hrs. 19 min. Indian Standard Time, showed a considerable difference, occasionally so much as 0.8 of a second, when compared about an hour later with the Nauen signals (international system), which end at Greenwich midnight. The o rate of the clock is so small that during the interval of an hour the clock developed negligible error; the difference between the two stations was consequently considered unfortunate, although this difference was ordinarily small.
