The EXEC statement TIME parameter specifies a limit on the processor time used by the related step. With any kind of restart, the entire value of the limit specified for the job step applies to the restart step. For a deferred restart, you may specify a limit different from the limit originally specified.

If the processor time used by a step exceeds the specified limit while a checkpoint entry is written, the entry is invalid and an abnormal termination occurs. You cannot do an automatic restart in this case but you can do a deferred checkpoint restart from an earlier checkpoint.
