- `cpu_times!sys::UInt64`: Time spent in system mode. CPU state shows the amount of CPU time used by the kernel.
- `cpu_times!idle::UInt64`: Time spent in idle mode. CPU state shows the CPU time that's not actively being used.
- `cpu_times!irq::UInt64`: Time spent handling interrupts. CPU state shows the amount of time the CPU has been servicing hardware interrupts.

The times are in units of `1/Sys.SC_CLK_TCK` seconds if `Sys.SC_CLK_TCK > 0`; otherwise they are in
unknown units.

    Sys.username()::String

Return the username for the current user. If the username cannot be determined
or is empty, this function throws an error.

To retrieve a username that is overridable via an environment variable,
e.g., `USER`, consider using
```julia
user = get(Sys.username, ENV, "USER")
```

!!! compat "Julia 1.11"
    This function requires at least Julia 1.11.
