This was IZ 1664 in project gridengine.

A test should be added to testsuite to detect possible bugs with resource
reservation due to the difference between net and gross job runtimes.
The new sched_conf(5) parameter "DURATION_OFFSET" allows dealing with those
differences. To cause a high difference between net and gross job runtimes a
queue configuration such as

   prolog                /bin/sleep 5
   epilog                /bin/sleep 5

can be used. If a job that requests requested reservation is delayed repeatedly

> grep ^41647 $SGE_ROOT/default/common/schedule | cut -f 1-5 -d: | uniq
41647:1:RESERVING:1118756149:3610
41647:1:RESERVING:1118756150:3610
41647:1:STARTING:1118756147:3610
41647:1:RUNNING:1118756147:3610

this is an outcome of a too low duration offset and could be used to detect bug
#1662.
