What unit is used to display Redis CPU usage

I ran the command INFO CPU in the Redis CLI and got the output shown below:

used_cpu_sys:4785.73
used_cpu_user:4843.73
used_cpu_sys_children:0.00
used_cpu_user_children:0.00

My question is: what is the unit used for these figures?

Is it CPU time, or CPU consumption or something else?

Answer

It is the CPU time (expressed in seconds) accumulated since the launch of the Redis instance, as reported by the getrusage() call.
