I overlooked it.
May #18331 be better?
----------------------------------------
Feature #18033: Time.new to parse a string
https://bugs.ruby-lang.org/issues/18033#change-95085
* Author: nobu (Nobuyoshi Nakada)
* Status: Open
* Priority: Normal
----------------------------------------
Make `Time.new` parse `Time#inspect` and ISO-8601 like strings.
* `Time.iso8601` and `Time.parse` need an extension library, `date`.
* `Time.iso8601` can't parse `Time#inspect` string.
* `Time.parse` often results in unintentional/surprising results.
* `Time.new` also about 1.9 times faster than `Time.iso8601`.
```
$ ./ruby -rtime -rbenchmark -e '
n = 1000
s = Time.now.iso8601
Benchmark.bm(12) do |x|
x.report("Time.iso8601") {n.times{Time.iso8601(s)}}
x.report("Time.parse") {n.times{Time.parse(s)}}
x.report("Time.new") {n.times{Time.new(s)}}
end'
