This structure contains the following instance variables and the corresponding accessors:

`utime` | Amount of User CPU time, in seconds
`stime` | Amount of System CPU time, in seconds
`cutime` | Completed child processes' User CPU time, in seconds (always 0 on Windows NT)
`cstime` | Completed child processes' System CPU time, in seconds (always 0 on Windows NT)

See also `Struct` on page 380 and `Time.times` on page 393.
