I want to trigger my functions or node at specific time, to be exactly, I need to computer something at every HOUR and every DAY.
If time is at [00:00:00, 01:00:00,02:00:00 and so on and so forth], I want my function to run at that specific time.
Same thing goes on every day situation, I want that everyday my function runs.
I am thinking that I can do this by simple have Inject node w/ interval and use a function node to check the current time.
But I am looking if someone has a better solutions for this?
For simple regular intervals as you describe you can use an Inject node set to fire every hour and select Interval Between Times and time range 00:00 to 00:00 every day and that will fire every hour on the hour.
