- If the first flow-file is timestamped 12:12:00 21st March 2007 and one of the report types specified is hourly reports, then the first report will come out at 13:00:00. After that all reports will keep coming out at 14:00:00, 15:00:00 and so on for the regular clock hours.
- Similarly for the above example if 15 minute reports are also specified then the first report will come out at 12:15:00 i.e. after only two flow files. However after that reports will keep coming out after 15 minutes at 12:30:00 and 12:45:00 etc .
- Again taking the above example, if three-hourly reports are also specified then the first report will come out at 15:00:00 and then at 18:00:00
- Similarly if daily reports are specified then the first report will come out for as soon as the final flow-file for 21st March 2007 has been processed. ( Note that if the earlier system were in place, then in this case the first daily report would have come out at 12:12:00 22nd March 2007)
