How to delay to start mission until time which set?



I want to start mission at time which I set.
So I try to upload MAV_CMD_NAV_DELAY, with parm1 is -1 and set param2~4 some UTC Time. As I expected, my drone(in SITL) start mission that time uploaded. But, doesn’t react anything my drone. How to ready to fly specific UTC time?


I don’t think this command is supported by PX4, at least from a quick search on GitHub I didn’t find much.

I think you need to implement that logic either in your ground station or your script or try to add it to PX4. Pull requests would be welcome!
