1 minute, 60 seconds, 60 thousand milliseconds. I work with computer systems that monitor themselves to make sure they don’t take more than 10 milliseconds. At 50 milliseconds, they would raise alarms.

It takes 100 milliseconds to blink.

So, we’d notice pretty much immediately :)

And then all networked computers that assume a response within 30 seconds would go bonkers and maybe need to be restarted.

I’d react by assuming IT misconfigured the Network Time Protocol service that keeps machine clocks synced and inform them.
