问题：以Unix时间戳格式获取当前GMT时间的最简单方法是什么？
Python提供不同的套餐（datetime，time，calendar），可以看出这里为了应对时间。我通过使用以下命令获取当前GMT时间犯了一个大错误time.mktime(datetime.datetime.utcnow().timetuple())
在Unix时间戳中获取当前GMT时间的简单方法是什么？
Python provides different packages (datetime, time, calendar) as can be seen here in order to deal with time. I made a big mistake by using the following to get current GMT time time.mktime(datetime.datetime.utcnow().timetuple())
What is a simple way to get current GMT time in Unix timestamp?

我将使用time.time（）获得自该纪元以来的时间戳（以秒为单位）。
import time
time.time()
输出：
1369550494.884832
对于大多数平台上的标准CPython实现，这将返回UTC值。
I would use time.time() to get a timestamp in seconds since the epoch.
import time
time.time()
Output:
1369550494.884832
For the standard CPython implementation on most platforms this will return a UTC value.

import time
int(time.time())
输出：
1521462189
import time
int(time.time())
Output:
1521462189

这有帮助吗？
from datetime import datetime
import calendar
d = datetime.utcnow()
unixtime = calendar.timegm(d.utctimetuple())
print unixtime
如何将Python UTC日期时间对象转换为UNIX时间戳

或者只是简单地使用datetime标准模块
In [2]: from datetime import timezone, datetime
...: int(datetime.now(tz=timezone.utc).timestamp() * 1000)
...:
Out[2]: 1514901741720
您可以截断或乘以所需的分辨率。此示例输出毫。
如果您想要正确的Unix时间戳（以秒为单位），请删除* 1000
Or just simply using the datetime standard module
In [2]: from datetime import timezone, datetime
...: int(datetime.now(tz=timezone.utc).timestamp() * 1000)
...:
Out[2]: 1514901741720
You can truncate or multiply depending on the resolution you want. This example is outputting millis.
If you want a proper Unix timestamp (in seconds) remove the * 1000

python2和python3
最好使用时间模块
import time
int(time.time())

您还可以使用datetime模块，但是当您使用strftime（’％s’）时，strftime会将时间转换为本地时间！
python2
from datetime import datetime
datetime.utcnow().strftime('%s')
python3
from datetime import datetime
datetime.utcnow().timestamp()
python2 and python3
it is good to use time module
import time
int(time.time())
1573708436
you can also use datetime module, but when you use strftime(‘%s’), but strftime convert time to your local time!
python2
from datetime import datetime
datetime.utcnow().strftime('%s')
python3
from datetime import datetime
datetime.utcnow().timestamp()

我喜欢这种方法：
import datetime, time
dts = datetime.datetime.utcnow()
epochtime = round(time.mktime(dts.timetuple()) + dts.microsecond/1e6)
此处发布的其他方法不能保证在所有平台上都具有UTC，或者只能报告整秒。如果您想获得完整的分辨率，则可以达到微秒级。
I like this method:
import datetime, time
dts = datetime.datetime.utcnow()
epochtime = round(time.mktime(dts.timetuple()) + dts.microsecond/1e6)
The other methods posted here are either not guaranteed to give you UTC on all platforms or only report whole seconds. If you want full resolution, this works, to the micro-second.

from datetime import datetime as dt
dt.utcnow().strftime("%s")
输出：
1544524990

#First Example:
from datetime import datetime, timezone
timstamp1 =int(datetime.now(tz=timezone.utc).timestamp() * 1000)
print(timstamp1)
输出：1572878043380
#second example:
import time
timstamp2 =int(time.time())
print(timstamp2)
输出：1572878043
- 在这里，我们可以看到第一个示例比第二个示例提供了更准确的时间。
- 在这里，我正在使用第一个。
#First Example:
from datetime import datetime, timezone
timstamp1 =int(datetime.now(tz=timezone.utc).timestamp() * 1000)
print(timstamp1)
Output: 1572878043380
#second example:
import time
timstamp2 =int(time.time())
print(timstamp2)
Output: 1572878043
- Here, we can see the first example gives more accurate time than second one.
- Here I am using the first one.

至少在python3中，这有效：
>>> datetime.strftime(datetime.utcnow(), "%s")
'1587503279'
At least in python3, this works:
>>> datetime.strftime(datetime.utcnow(), "%s")
'1587503279'
