Subject: [ruby-core:28603] [Bug #2952] Time.strftime format %N

Issue #2952 has been updated by Shugo Maeda.


> There seems to be some rouding errors with the %N formatter for Time->strftime
> t1 = 1236922275.8516
> t2 = Time.at(t1)

It is because a Float can't represent 1236922275.8516 exactly, isn't it?
The following script prints "1236922275.851600".

$ cat t.rb
t = Time.at(1236922275, 851600)
puts t.strftime("%s.%6N")
$ ruby-trunk -v t.rb
ruby 1.9.2dev (2010-03-10 trunk 26866) [i686-linux]
1236922275.851600
