User and system time should be in consistent time units #408
Description
The "user" and "system" time should be reported in the same unit as mean, stddev, min and max. They should also follow --time-unit, if specified.
Example 1:
▶ hyperfine --runs 2 'stress --cpu 1 --timeout 1'
Benchmark 1: stress --cpu 1 --timeout 1
Time (mean ± σ): 1.002 s ± 0.002 s [User: 993.7 ms, System: 1.0 ms]
Range (min … max): 1.000 s … 1.003 s 2 runs
Example 2:
▶ hyperfine --runs 2 'stress --cpu 1 --timeout 2' --time-unit millisecond
Benchmark 1: stress --cpu 1 --timeout 2
Time (mean ± σ): 2000.4 ms ± 0.5 ms [User: 1.983 s, System: 0.003 s]
Range (min … max): 2000.0 ms … 2000.8 ms 2 runs
