You can’t rely on the hearbeat running every second. I think it would be better to use Time.now() to record the time of the last hearbeat and see if this hearbeat needs to do work.

You should be able to adapt this example to do what you want, by looking at the time the hearbeat is invoked. [image] Internet Computer | Documentation Documentation for the internet computer.

Right, that was my question. On mainnet, should I expect the function to run once every second? That way i can set a check for n >= 60, and if the condition is met, set n to 0 and execute my logic, otherwise just increment n

Is heartbeat live in motoko on main net now?

Is Time.now() in Motoko calling ic0.time? Not very familiar with Motoko Otherwise wouldn’t Time.now() introduce local non -determinizm when used to make decisions in execution? At least that is what I got from @akhilesh.singhania recent video cast on YouTube. @nomeata suggests here([quote=“nomeata…

It is the time of the block which the proposer sets and validators endorse.

[image] Time - Docs and Language Support I haven’t done a complete tear down of how the IC handles messages yet, so please correct me if I’m making poor assumptions. In eth all the nodes have to agree that a block is valid. There for the block has to provides some assumpt…

Yeah, Time.now() calls ic0.time.

@Icdev2dev , you seem to be repeatedly worried about non-determinism creeping in if canisters do the wrong thing (here, in the discussion of stable memory). Rest assured: Canisters run in a carefully constructed sandbox, and nothing they can do can endanger determinism. (Else the whole IC would fall …

Thanks, @nomeata for the reassurance! Yes, I WAS worried. Your words have put this to rest.
