For those who searches for an answer without parsing and loosing milliseconds, given dt_obj is a datetime:

python3 only, elegant

int(dt_obj.timestamp() * 1000)

both python2 and python3 compatible:

import time

int(time.mktime(dt_obj.utctimetuple()) * 1000 + dt_obj.microsecond / 1000)

For Python2 7 - modifying MYGz s answer to not strip milliseconds   from datetime import datetime  d   datetime strptime  20 12 2016 09 38 42 76     d  m  Y  H  M  S  f   strftime   s  f   d in ms   int float d  1000  print d in ms   print datetime fromtimestamp float d      Output   1482248322760 2016-12-20 09 38 42 760000

For Python2 7  You can format it into seconds and then multiply by 1000 to convert to millisecond   from datetime import datetime  d   datetime strptime  20 12 2016 09 38 42 76     d  m  Y  H  M  S  f   strftime   s   d in ms   int d  1000 print d in ms   print datetime fromtimestamp float d      Output   1482206922000 2016-12-20 09 38 42

In Python 3 this can be done in 2 steps    Convert timestring to datetime object Multiply the timestamp of the datetime object by 1000 to convert it to milliseconds    For example like this   from datetime import datetime  dt obj   datetime strptime  20 12 2016 09 38 42 76                                d  m  Y  H  M  S  f   millisec   dt obj timestamp     1000  print millisec    Output   1482223122760 0   strptime accepts your timestring and a format string as input  The timestring  first argument  specifies what you actually want to convert to a datetime object  The format string  second argument  specifies the actual format of the string that you have passed   Here is the explanation of the format specifiers from the official documentation     d - Day of the month as a zero-padded decimal number   m - Month as a zero-padded decimal number   Y - Year with century as a decimal number  H - Hour  24-hour clock  as a zero-padded decimal number   M - Minute as a zero-padded decimal number   S - Second as a zero-padded decimal number   f - Microsecond as a decimal number  zero-padded on the left

You need to parse your time format using strptime    gt  gt  gt  import time  gt  gt  gt  from datetime import datetime  gt  gt  gt  ts  ms    20 12 2016 09 38 42 76  split       gt  gt  gt  ts  20 12 2016 09 38 42   gt  gt  gt  ms  76   gt  gt  gt  dt   datetime strptime ts    d  m  Y  H  M  S    gt  gt  gt  time mktime dt timetuple    1000   int ms  10 1482223122760 0
