Question

为什么utcnow关闭1小时？

代码：

from datetime import *
print datetime.utcnow()

结果：

2016-11-25 10:28:04.655978

Servertime：

Fri Nov 25 11:28:11 CET 2016

Answer 1

因为CET是UTC + 1

Answer 2

datetime.utcnow()返回UTC（协调世界时）时间：UTC Time definition

与服务器同时使用datetime.now()。

In [8]: from datetime import datetime

In [9]: datetime.utcnow()
Out[9]: datetime.datetime(2016, 11, 25, 10, 32, 18, 288195)

In [10]: datetime.now()
Out[10]: datetime.datetime(2016, 11, 25, 11, 32, 22, 336213)

Answer 3

发生这种情况是因为您的服务器处于不同的时区。（CET = +1）

>>> from datetime import datetime
>>> 
>>> datetime.utcnow()
datetime.datetime(2016, 11, 25, 10, 35, 33, 931951)
>>>

使用pytz模块更改时区

pip install pytz

Answer 4

您也可以使用时区，如

from datetime import datetime
from pytz import timezone

fmt = "%Y-%m-%d %H:%M:%S %Z%z"

# Current time in UTC
now_utc = datetime.now(timezone('UTC'))
print now_utc.strftime(fmt)

# Convert to US/Pacific time zone
now_pacific = now_utc.astimezone(timezone('US/Pacific'))
print now_pacific.strftime(fmt)

# Convert to Europe/Berlin time zone
now_berlin = now_pacific.astimezone(timezone('Europe/Berlin'))
print now_berlin.strftime(fmt)

datetime.utcnow（）关闭1小时
