我使用 PHP 手册中的一些代码进行异常测试，但收到一些奇怪的消息。

这是代码：

function inverse($x) {
    if (!$x) {
        throw new Exception('Division by zero.');
    }
    else return 1 / $x;
}

try {
    echo inverse(5) . "\n";
    echo inverse(0) . "\n";
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

// Continue execution
echo 'Hello World';

这是输出：

0.2

有没有办法更改Javascript的getTimezoneOffset以返回不同的时区偏移量？

Fox的例子,我当地的时区是GMT-8,但我希望Date.getTimezoneOffset()返回GMT-1,所以我这样做如下:

var timeZone1 = new Date(Date.parse("2011-01-01T00:00:00-01:00"));
document.write("The local time zone is: GMT " + timeZone1.getTimezoneOffset()/60);
//show:The local time zone is: GMT-8

那么,如何让它显示GMT-1？

我是python的新手，我正在学习标准库。

每当我运行下面的代码时，它总会引发，AttributeError... 并且import命令似乎出了点问题。

另外，我尝试在交互式解释器上运行它，并且效果很好。

样例代码

import tempfile
import os

#temp = tempfile.TemporaryFile()
temp = tempfile.mktemp()

print "tempfile","=>",temp

file = open(temp,"w+b")
file.write("*" * 1000)
file.seek(0)
print len(file.read()),"byte"
file.close()

try:
   os.remove(temp)
except OSError:
   pass

错误输出

  File "tempfile.py", line 1, in <module>
    import tempfile
  File "/home/zhkzyth/codeRep/pytest/tempfile.py", line 5, in <module>
