delta-time The time interval at which output is written from the output buffer to the batch job log file. If no delta time is specified, the information is written in the output buffer to the log file, but the output rate is not changed from the default of once per minute. Specify delta-time as [dddd-][hh:mm:ss.cc]. For more information on delta time, see the OpenVMS User's Manual or the online help topic Date.
