""" Schedules downtime for a specified service. If the "fixed" argument is set
to one (1), downtime will start and end at the times specified by the
"start" and "end" arguments.
Otherwise, downtime will begin between the "start" and "end" times and last
for "duration" seconds. The "start" and "end" arguments are specified
in time_t format (seconds since the UNIX epoch). The specified service
downtime can be triggered by another downtime entry if the "trigger_id"
is set to the ID of another scheduled downtime entry.
Set the "trigger_id" argument to zero (0) if the downtime for the
specified service should not be triggered by another downtime entry.
