RTC, usage... commands on specific time!

Hi i want some help. I want to create commands that could be excecuted in specific timming! Millis is not helping at all, so i turnend to RTC. The only problem is that i dont know how can I reate a "timelime" during which would be excecuted several commands such as analog and digital readings and digital- analog acts. I'm new, so be cool if my questions seem dammy. Help please.

Why didn't millis() work? It is a lot easier to use than an RTC, and will probably have the same issues.

This needs more detail. How would YOU perform the task(s) that you want the Arduino to perform?

Sadly, you haven't posted this "non-working" code.

Please use code tags.
