O:-Please inform how correct time transmitted
to the country What advantage standard time over sun
time and when was present standard time adoptedl
A:-The time service of the u S. Naval Observatory has
continued regularly to send daily telegaphc signals
sevenyfh meridian time with an average error for
the year of only Os IS The widespread importance
service shown by the fact that absolute standard
time not only for navigaors all the principal eapors but
for the entire except the Pacific Coast which gets
similar signal from the Naval Observatory Mare Island
Yard Moreover all of this invaluable service rendered
the country no expense whatever the Government mas
much is merely incidental the work and facilities equ
ed tor the rating of chronometers for vessels.
To illustrate the wide distribution time signal is
of Interest to record the fact that goes daily
wires OF the Western Union Telegraph Company the Postal
Telegraph Company, the American Telephone Telegraph
Company, the electrical department of the District
ba and the National Electric Supply Company There
18 Government me-bas 49, 900 public and pr
vate clocks corrected daily by naval time signals.
The desrabily of using uniform standard of time, in
dependent OF local tlme was recognized very early date
The differences of local time arise motion
as time measure We call the time when is
opposite the meridian of the place where living,
consequence of the east to west the more
eastey OF the two places will have the earlier tme the differ
in hours being exactly 15h of the longitudinal difference
in degrees In other WORDS Is degrees of longitude correspond
to time difference of one hour. Peculiar difficulties
countered in this country of its longitudinal
tent and the became
sion of the railroad and telegraph systems.
The movement which resulted in the adoption of pres
ent time system be said to have originated report
the subject by the American Meteorological Society,"
submitted meeting of the General Time Convention held
Oct 49, 1884, proposing single standard whole
country and suggesting the hour theory alternative propo
Sltlon he matter was referred to the secretary, Mr. w. T.
Aen and communications invited from parties interest
ed. The proposal fix standard of time whole
country supported by many competent authorities; but al
though there was much to recommend from scientific point
of vew found be impracticable account of the
many discrepancies which would between time by the
clock and solar time The which found favor,
and finally adopted the division country
into four time sections each of Is degrees longitude a de-
gees 80 minutes each side of the median commencing
with the 18th meridian Inside each of these sections
to be uniform the time of each section differing from that
it by exactly hour scheme up
with these principles and meeting of the
held in April 1885, the following resolutions adopted:
o. That all roads using Boston, New York, Phila-
depha Baltimore Toronto Hamilton, Washington time
Standard based meridans of those points ada
thereto shall be governed by the 18th meridian
time Il minutes slower than New York time.)
(2 That all roads using Columbus, Savannah, At
lana Cincinnati, Louisville Indianapolis Chicago, Jefferson
City, ST. Paul. Kansas City time. standards based upon
medans adjacent thereto shall be by the Goth meridian
time, be called Central me hour slower than Eastern
time and minutes slower than Chicago time.
(3.) That of the abovenamed sections the roads
shall be by the lO5th and 10th meridian respective
y, and three hours slower than Eastern time,
a. That all changes from hour standard another
shall be made the emn of roads the ends divisions
The advantages of this method of reckoning
Every town, instead of regulating its business by
local time, the time of the standard med
ans, and the difference in time actual any cities
will be number of hours instead of number hours
minutes and seconds. traveller therefore, wishing
his watch need only change the hour without paying
ention to the minutes. Having proceeded g., from New
York any within the Central time zone, he has simply
his watch hour slow of New York time and need
compare it with any of the local clocks.
