Change the command from intval() to floor() and see if the problem goes away. It's here:

        $allindex    = ($elements - 1) * $p;
        $intvalindex = floor($allindex);
        $floatval    = $allindex - $intvalindex;

What's on line 5203 in your version?

In my version of lib/functions.php $time %= $mod; is line 5269. Can you confirm?

I did another update following your back-trace and not the line numbers since they don't even match on the 1.2.x branch.

Nope. I changed this to $time = floor($mod);
and it is solved my errors.
That's right?

@TheWitness

Well, that's one, but I also looked at the backtrace and what is happening is that the hosts sysUptimeInstance was being divided by 100, which is proper, and that converted the "time" value that was sent to the next function was a float, which having a modulus on a float could also throw the loss of precision error. So, I converted it to an integer (I think). You need to make the next update and see if the backtraces go away.

I may have to add use intval() instead of floor() or round(). You need to continue to test. I don't have a PHP8.1 env at the moment.

Let's not mess with tickets. I'm only caring about 1.2.x in this ticket.

Right now, I'm not even working on 1.3 tickets. @netniV and I have to get it back into shape after the 1.2.20 release.

Good to hear. I'll look at your issue on Import as well.
