Unless their need is for it to go off on a regular schedule. |
so what is your proposal then? |
Any of the OS level schedulers. On Unix cron is a popular choice because it's ubiquitous, on Windows there's the Windows Scheduler and on z/OS there's CA7 (or something - I've never seen a z/OS installation that didn't have a complex batch schedule).
All of these tools will handle unexpected events, missed schedule dates and support more complex scheduling scenarios than the simple (but entirely valid) one described by the OP. An more complex but equally plausible example would be once an hour between 8am and 5pm on weekdays.
Obviously the Windows Scheduler does this as effectively and reliably as any piece of Windows software. But it's still less vulnerable to external events than the Timer node. |
yes, of course, you can always use a chauffeur driven rollers to go to the local supermarket two blocks down the road... but I doubt that is what the Op is looking for. |

It certainly never hurts to raise additional concerns.

I would not describe cron as "a chauffeur driven roller"
I stand by my original objection that if you want the flow to go off once an hour (and worse still, at a fixed point in the hour) the Timer node can't be relied upon to do that.

so, what is the exact requirement then? |

Only the OP knows for sure, but this is what was said
| Quote: |
| create a one output file for every hour |
So, plenty of room to decide if the requirements are actually met by the Timer nodes and their level of reliability.

and he/she also said:
| Quote: |
| and used Timeout Notification node |
so he/she already have a working flow, only wanted to know how to produce only one header. |

I suspect you are being sarcastic again.
