I have set some seconds but sometimes it is delayed more than 10 minutes. I know that delay_sec is not the accurate time because of the block production mechanism. The real time is much later than it should happen.
Answer from the telegram by admin Todd Fleming:
There is no guarantee that delayed transactions will execute on time, or at all. Trying to make guarantees like that would compromise the integrity of the chain.
