Setting when crossing time zones:
– When crossing time zones in an easterly direction, you should
simply set the time forward to the new local time.
– When crossing time zones in a westerly direction, you can
set the hands of your watch back to the actual time of day.
When doing this, however, you must not move back into the
calendar's automatic switching phase, i.e. beyond 2 a.m. If this
situation occurs when you are travelling west, you should set
the local time of your destination before 8 p.m. You must not
turn the hands back between 8 p.m. and 2 a.m.
