onOneServer clarification

[driade]

Hello, good morning.

I'm checking the docs about "onOneServer", as I'd like to have more than one server running the scheduler. As far as I've understood, and checked into laravel's code, the servers running the scheduler must have their clocks completely synchronized.

If not, it'd be possible for one server to run a task on minute "6:00", finish one second later, and then have another server run the same task because the clock is one second behind.

May someone help me understand if am I right?

If my above assumption is correct, shouldn't we have a new method to run the tasks "oncePerTime", as having the servers' time synchronized is difficult?

Thanks in advance.
