PARIS AND GREENWICH TIME.
The fact that Paris adopted Greenwich time not long ago causes an electric-light station to gain £500 a year, according to an estimate. The reason for this somewhat curious result lies in the ■ difference of time of burning electric lamps, and oven though this is very small, it figures up in a yearly estimate to quite an extent. Greenwich time of five o'clock corresponds to 5.10 Paris , time, . for instance. Lamps are turned on according to the amount of daylight, but offices close at a fixed hour. Should an office close at six o'clock it is evident that the lamps will have burned 10 minutes longer, owing to the change over to Greenwich time. The extra amount of current is naturally paid for by the users, so that this makes the central station gain about one per cent., and even ; this small difference applied to the case of an electric plant furnishing 15,000,000 kilowatts a year will aiva theabove increase. -•■ :, v ,: -: ■ ■ ■ " j .::■■,■ •.''.■■•-.■-■■■■ ■■■.'"■■i-.,..--" ■■-■:'' : '-<---.^e::^
