        # Benchmark::Tms.format

(from ruby core)
### Implementation from Tms
---
    format(format = nil, *args)

---

Returns the contents of this Tms object as a formatted string, according
to a `format` string like that passed to Kernel.format. In addition,
#format accepts the following extensions:

`%u`
:   Replaced by the user CPU time, as reported by Tms#utime.
`%y`
:   Replaced by the system CPU time, as reported by #stime (Mnemonic: y
    of "s*y*stem")
`%U`
:   Replaced by the children's user CPU time, as reported by Tms#cutime
`%Y`
:   Replaced by the children's system CPU time, as reported by
    Tms#cstime
`%t`
:   Replaced by the total CPU time, as reported by Tms#total
`%r`
:   Replaced by the elapsed real time, as reported by Tms#real
`%n`
:   Replaced by the label string, as reported by Tms#label (Mnemonic: n
    of "*n*ame")


If `format` is not given, FORMAT is used as default value, detailing the
user, system and real elapsed time.
