Python: strftime, gmtime not respecting timezone
提问by Shaun Budhram
import time
print time.strftime("%a, %d %b %Y %I:%M %p %Z", time.gmtime())
I live in California. For some reason, this code is reporting the time in GMT, instead of respecting the system time zone. I know that strftime knows I'm in pacific, because it still prints 'PST' at the end, but it's still 8 hours ahead. Is anyone else noticing this? Anyone know what's either wrong with my system or my code?
我居住在加利福尼亚州。出于某种原因，此代码以 GMT 报告时间，而不是遵守系统时区。我知道 strftime 知道我在太平洋，因为它最后仍然打印“PST”，但它仍然提前 8 小时。还有人注意到这一点吗？有人知道我的系统或我的代码有什么问题吗？
EDIT:
running dateat the command line gives me the correct date. Additionally, I've run this on two different computers (mac and linux) and they both report 8 hours ahead. Are you expected to correct for timezone before using strftime?
编辑：date在命令行上运行给了我正确的日期。此外，我已经在两台不同的计算机（mac 和 linux）上运行了它，它们都提前 8 小时报告。您是否希望在使用 strftime 之前更正时区？

time.gmtime()returns the time in UTC. What you need is time.localtime(), which istimezone-aware. This behaviour is well-documented in the timemodule documentation.
time.gmtime()返回 UTC 时间。你需要的是time.localtime()，它是时区感知的。这种行为在time模块文档中有详细记录。
EDIT:
编辑：
To convert any time.time()style timestamp to a struct_time, you can supply an argument to
time.localtime():
要将任何time.time()样式时间戳转换为 a struct_time，您可以为 提供一个参数
time.localtime()：
>>> print time.strftime("%a, %d %b %Y %I:%M:%S %p %Z", time.localtime(10.5))

To change the timezone on your unix system, do something like this:
要更改 unix 系统上的时区，请执行以下操作：
ln -sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
Browse around in /usr/share/zoneinfo/to find what you want and alter the command above
浏览/usr/share/zoneinfo/以找到您想要的内容并更改上面的命令
