<blockquote>
  <p>For a web application, flask is responsible for server side only.</p>
</blockquote>

<p>Your purpose can be achieved by using javascript to get client side time and passing it to server.</p>

<p><strong>Folder structure</strong></p>

<pre><code>.
├── app.py
└── templates
    └── index.html
</code></pre>

<p><strong>app.py</strong></p>

@app.route("/")
def index():
    return render_template("index.html")

@app.route("/getTime", methods=['GET'])
def getTime():
    print("browser time: ", request.args.get("time"))
    print("server time : ", time.strftime('%A %B, %d %Y %H:%M:%S'));
    return "Done"

blocks|key|3926495|text|使用客户端获取日期不是一个好方法，因为它不安全。我认为最好的方法是将本地服务器时间更新为您的时区，并使用Python+datetime库获取当前时间。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3926496|用户可以更改您的js文件，并将错误的日期时间传递给您的服务器！|3926497|entityMap|0|LINK|mutability|MUTABLE|url|https://www.programiz.com/python-programming/datetime^0|1G|F|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

<p>using client side to get date is not a good way as it's not safe.
I think best way is to update your local server time to your time zone and use <a href="https://www.programiz.com/python-programming/datetime" rel="nofollow noreferrer">Python datetime</a> lib to get current time.<br>
Users can change your js file and pass wrong date time to your server!</p>


<p>I'm building a Flask app in Python and I would like to save the user local time.</p>

<p>I thought of using this</p>

<pre><code>time.strftime('%A %B, %d %Y %H:%M:%S')
</code></pre>

<p>But this is giving me the server local time.</p>

我正在用Python构建一个Flask应用程序，我想节省用户的本地时间。我想用这个time.strftime('%A %B, %d %Y %H:%M:%S')但这给了我服务器的本地时间。
