What is the easiest way to get current GMT time in Unix timestamp format?
提问by Cory
Python provides different packages (datetime, time, calendar) as can be seen herein 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())
Python 提供了不同的包（datetime, time, calendar），可以在此处看到以处理时间。通过使用以下内容获取当前 GMT 时间，我犯了一个大错误time.mktime(datetime.datetime.utcnow().timetuple())

Does this help?
这有帮助吗？
from datetime import datetime
import calendar
d = datetime.utcnow()
unixtime = calendar.timegm(d.utctimetuple())
print unixtime

I would use time.time() to get a timestamp in seconds since the epoch.
我会使用 time.time() 来获取自纪元以来以秒为单位的时间戳。
import time
time.time()
Output:
输出：
1369550494.884832
For the standard CPython implementation on most platforms this will return a UTC value.
对于大多数平台上的标准 CPython 实现，这将返回一个 UTC 值。

I like this method:
我喜欢这个方法：
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.
此处发布的其他方法要么不能保证在所有平台上都能为您提供 UTC，要么只能报告整秒。如果你想要全分辨率，这可以工作到微秒。

Or just simply using the datetime standard module
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
You can truncate or multiply depending on the resolution you want. This example is outputting millis.
您可以根据所需的分辨率进行截断或相乘。此示例输出毫秒。
If you want a proper Unixtimestamp (in seconds) remove the * 1000
如果您想要一个正确的Unix时间戳（以秒为单位），请删除* 1000

#First Example:
from datetime import datetime, timezone
timstamp1 =int(datetime.now(tz=timezone.utc).timestamp() * 1000)
print(timstamp1)
Output: 1572878043380
输出：1572878043380
#second example:
import time
timstamp2 =int(time.time())
print(timstamp2)
Output: 1572878043
输出：1572878043
- Here, we can see the first example gives more accurate time than second one.
- Here I am using the first one.
- 在这里，我们可以看到第一个示例给出的时间比第二个更准确。
- 这里我使用的是第一个。

it is good to use time module
使用时间模块很好
import time
int(time.time())
1573708436
1573708436
you can also use datetime module, but when you use strftime('%s'), but strftime convert time to your local time!
您也可以使用 datetime 模块，但是当您使用 strftime('%s') 时，但 strftime 将时间转换为您的本地时间！

from datetime import datetime
datetime.utcnow().timestamp()

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