File.ctime

(::string | ::_ToPath | ::IO file_name) -> ::Time

File.ctime(file_name) → time

static VALUE
rb_file_s_ctime(VALUE klass, VALUE fname)
{
    struct stat st;

    if (rb_stat(fname, &st) < 0) {
        int e = errno;
        FilePathValue(fname);
        rb_syserr_fail_path(e, fname);
    }
    return stat_ctime(&st);
}

Returns the change time for the named file (the time at which directory information about the file was changed, not the file itself).

file_name can be an IO object.

Note that on Windows (NTFS), returns creation time (birth time).

Example

File.ctime("testfile")   #=> Wed Apr 09 08:53:13 CDT 2003
