Time Zone Dislocations
Travelers passing through many time zones by high speed
planes are subject to physiological and psychological changes that
may seriously affect their health or performance of duty. Medical
tests conducted by the Federal Aviation Agency and International
Civil Aviation Organization have shown that a minimum rest period
of 24 hours following rapid time zone change will restore most of
this metabolic upset.
A 24-hour rest period is provided for travelers who experience a
difference of five or more hours between local times at point where
travel commences and point of arrival on direct flights, or four or
more hours' difference on the final portion of a flight resumed after
an authorized rest stop. See section 1833. 3.
Where the purpose of the travel is to engage in international con-
ferences, negotiations, or consultation with foreign nationals, this
adjustment period is particularly important. Officials authorizing
such travel should make provision for this adjustment period in all
cases, unless prevented by emergency conditions.
Where frequent and continuous travel is an integral part of the
work assignment, offices preparing travel schedules should take
the time zone dislocation factor into consideration when possible.

**1833.3 Time Zone Dislocations
Travelers flying without interruption, except
for flight connections, on a direct route with
a difference of five or more hours between
local time at point of departure when travel
began and local time when arriving at the
temporary or permanent duty point should,
whenever possible, arrange departure to
allow arrival at destination a full day before
commencing duty.
When the flight is of such duration that it
includes an authorized rest stop, as pro-
vided in section 1833. 2, the same considera-
tion should be given at the conclusion of the
trip, provided there is a difference of four
or more hours between local time at point
of departure when travel was resumed and
local time at destination point when arriving.
In cases meeting either of these criteria,
excused absence without charge to leave may
be granted for any part of the 24-hour adjust-
ment period following arrival at the duty
point which happens to fall within working
hours.
Per diem during the adjustment period is
payable to temporary duty travelers.**
