What is the easiest way to get current GMT time in Unix timestamp format?

问题

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?

回答1:

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.

回答2:

import time

int(time.time())

Output:

1521462189

Does this help?

from datetime import datetime
import calendar

d = datetime.utcnow()
unixtime = calendar.timegm(d.utctimetuple())
print unixtime

How to convert Python UTC datetime object to UNIX timestamp

回答4:

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

回答5:

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.

回答6:

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

Output:

1544524990

回答7:

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()

#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.
