I use "time" to run some performance tests in our project under WSL2, but the result looks weird:  the value of "real" is far from the sum of "user" + "sys".

sched clock callback should return time with nano second as unit but 
current hv callback returns time with 100ns. Fix it.

Hi Yubo,
I'm curious how you found the bug? :-) Did you notice some kind of symtom?

Thanks,
