I've built a program and I want to run it every 5 mins at round time (**:00, **:05, **:10, ..., not **:01, **:06, **:11, ... or **:03, **:08, **:13, ...).
As I've read, it's better to use systemd than crontab, so I want to use systemd. And I understand how to launch program every 5 mins, but it doesn't launch at round time. I know I can try to launch the program at **:00 so next time it will launch at **:05 and etc, but it seems to be a too silly way.
How do I launch program like this with systemd? Or I can't do it with systemd and I should use crontab?
