_API JobChangeTimeRequest Description
Subject to the rules for the options, changes to the job’s start time, arrival time and finish time, as well as any changes to its dispatch status, will be dispatched and, if the job is in jeopardy, the jeopardy conditions will appear on the Gantt jeopardy report in the normal way. For example: if a job is earmarked, its start time is changed by JobChangeStartTimeRequest (with SP_OptJobSetStatusBack
 set) so that it then falls outside the inform lead time, the job will subsequently be unearmarked. Alternatively, if a job’s completion time is made later in time and if it then overlaps another job, this will be reported as being in jeopardy.
Changes to the job’s start time, arrival time and finish time, as well as any changes to its dispatch status will subsequently become visible on the Gantt chart.
