Raku perl 5和perl 6下的文件ctime不同

操作系统：Windows Server 2012 R2标准 FS:NTFS

==perl5

e:\temporary>perl -v
This is perl 5, version 22, subversion 0 (v5.22.0) built for MSWin32-x64-multi-thread

e:\temporary>type ctime.pl
use File::stat;
use Time::Piece;

my $fn1 = 't:\temporary\tia\Энергия\print.pdf';
my $fn2 = 't:\temporary\tia\Энергия\kl_to_1c.txt';
for ($fn1,$fn2) {
    my $fs = stat($_);
    print "$_\n";
    print 'changed  ',gmtime($fs->ctime)->datetime,"\n";
    print 'modified ',gmtime($fs->mtime)->datetime,"\n";
    print 'accessed ',gmtime($fs->atime)->datetime,"\n";
}

从perl6：

 changed  2016-06-30T16:38:48Z
 modified 2016-06-30T16:38:48Z
 accessed 2016-06-30T16:38:42Z

2） 几分钟后编辑此文件。差异将更加明显。 从perl5：

  changed  2016-06-30T16:38:42 <==
  modified 2016-06-30T16:49:17
  accessed 2016-06-30T16:38:42

这可能是源于libuv的错误（请参阅：）。即使是这样，它也不应该进入Perl6代码。请针对Rakudo（请参阅：）提交一份错误报告。

仅调用文件上的

stat

命令的结果是什么？我使用UTC/GMT更新了示例。由于Windows没有“stat”使用cgwin/babun shell获取数据，因此文档中提到

ctime

是不可移植的。查看下表，它提到

ctime

是Windows上的创建时间。Rakudo可能会做一些不同的事情来尝试更便携。（也可能是虫子）嗯。。我确信perl6是返回正确值的那个？它似乎返回了不同的时间，以便将

цццццц\klцu转换为_1c.txt

，更不用说它似乎与cygwin的统计输出一致。。也许我弄错了？@Timbus这件事没有错也没有对。如何将这4个时间戳映射到3个posix时间戳是个人偏好的问题。在没有充分理由改变Perl 5和Perl 6之间的行为的情况下，我们希望尽可能接近Perl 5，以便在使用Inline:：Perl5时更容易从5移植到6，并避免陷阱。Perl 5中的正确方法也是使用Win32API:：File:：Time。Perl 6也是如此，非常欢迎您编写该模块。：）
