Feature #18033

Updated by nobu (Nobuyoshi Nakada) 3 months ago

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' 
                        user       system        total          real
