TIME DIFFERENCE ADJUSTMENT
How to determine the time
differences between two areas
Before making the time difference adjustment, it is
necessary to obtain the time differences between the
two areas.
Even if the hour hand is turned to show the time of
any place, AM/PM and the date of the place may not
be adjusted properly. Before setting the hand, there-
fore, be sure to find the time difference between two
areas following the procedure below.
How to calculate the time differences
Assuming that you move from time zone "A" to time
zone "B" and that the time difference from GMT for the
two time zones are "a" and "b", respectively, time dif-
ference between them can be obtained from the fol -
lowing formula: b
Example If you move from Japan to New York
Time difference from GMT for Japan,
time zone A: a
Time difference from GMT for New York,
time zone B: b
Time difference between the two cities is:
