时区感知，零外部依赖:

from datetime import datetime, timezone

def utc_now():
    return datetime.utcnow().replace(tzinfo=timezone.utc)

时区感知，零外部依赖:

from datetime import datetime, timezone

def utc_now():
    return datetime.utcnow().replace(tzinfo=timezone.utc)

import datetime
import pytz

# datetime object with timezone awareness:
datetime.datetime.now(tz=pytz.utc)

# seconds from epoch:
datetime.datetime.now(tz=pytz.utc).timestamp() 

# ms from epoch:
int(datetime.datetime.now(tz=pytz.utc).timestamp() * 1000) 

时区感知的datetime对象，不像datetime.utcnow():

from datetime import datetime,timezone
now_utc = datetime.now(timezone.utc)

从Unix纪元开始的时间戳，单位为毫秒:

datetime.now(timezone.utc).timestamp() * 1000

为什么所有回复基于datetime而不是时间? 我认为这是简单的方法!

import time
nowgmt = time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime())
print(nowgmt)

datetime。您已经可以使用方法strftime导出到时间戳。下面是函数示例:

import datetime
def UtcNow():
    now = datetime.datetime.utcnow()
    return int(now.strftime("%s"))

如果您想要微秒，您需要更改导出字符串并将其强制转换为浮点类型，例如:
