If i understood your question then .

如果我理解你的问题那么。

How can I convert in UTC

如何转换为UTC

from datetime import datetime
from pytz import timezone

date_str = "2009-05-05 22:28:15"
datetime_obj = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S")
datetime_obj_utc = datetime_obj.replace(tzinfo=timezone('UTC'))
print datetime_obj_utc.strftime("%Y-%m-%d %H:%M:%S %Z%z")

You need to install pytz

你需要安装pytz

If you want to add some timestamp in your current time .

如果要在当前时间添加一些时间戳。

Do something like this

做这样的事情

future = datetime.datetime.now() + datetime.timedelta(minutes=5)
return time.mktime(future.timetuple()).

Please go through this article time.mktime

请仔细阅读本文time.mktime

You generally want the date to already be in UTC (or explicitly offset from UTC) on the server, then converted at the last second (pun intended) to the client's local timezone.

您通常希望日期在服务器上已经是UTC(或明确偏离UTC),然后在最后一秒(双关语)转换为客户端的本地时区。

With jquery-timeago, assuming the date is already (relative to) UTC, you can format it as such (in Python, server-side) and jquery-timeago should figure out the rest correctly.

使用jquery-timeago,假设日期已经(相对于)UTC,您可以将其格式化(在Python中,服务器端),jquery-timeago应该正确地找出其余部分。

Here's what I use to format UTC dates in my own HTML templates:

以下是我在自己的HTML模板中格式化UTC日期的方法:

{{ activity.date.isoformat() + 'Z' }}
