Turning off "Display the time with seconds" lowers the 1% CPU load to 0% for me.

When Microsoft finally added official support for that feature, people were mocking them for how long it took them, "how many resources could it possibly consume". Here we see the result.

Settings > Control Center (scroll down to bottom) > Clock Options > Display the Time in Seconds

Nice find. I always have seconds displayed, but disabling it reduced the CPU load to 0%

Just be aware that 1% on modern multi-core systems is not a lot. The macOS activity monitor doesn't calculate the average percentage over all cores, instead (AFAIK) a process on e.g. a M1 Pro/Max can use up to 1000% if it utilizes all 10 cores.

Stuff like this will be run on the efficiency cores, I doubt it will have a lot of impact on anything.

You can see the usage of efficiency vs performance cores by using Activity Monitor => Window => CPU History

I have the clock disabled entirely and it still sits at 1% CPU.

or change it to display the analog clock instead
