How to get UTC time in Python

Question

I ve search a bunch on StackExchange for a solution but nothing does quite what I need   In JavaScript  I m using the following to calculate UTC time since Jan 1st 1970   function UtcNow         var now   new Date        var utc   Date UTC now getUTCFullYear    now getUTCMonth    now getUTCDate    now getUTCHours    now getUTCMinutes    now getUTCSeconds    now getUTCMilliseconds         return utc      What would be the equivalent Python code

In the form closest to your original   import datetime  def UtcNow        now   datetime datetime utcnow       return now   If you need to know the number of seconds from 1970-01-01 rather than a native Python datetime  use this instead   return  now - datetime datetime 1970  1  1   total seconds     Python has naming conventions that are at odds with what you might be used to in Javascript  see PEP 8  Also  a function that simply returns the result of another function is rather silly  if it s just a matter of making it more accessible  you can create another name for a function by simply assigning it  The first example above could be replaced with   utc now   datetime datetime utcnow

From datetime datetime you already can export to timestamps with method strftime  Following your function example   import datetime def UtcNow        now   datetime datetime utcnow       return int now strftime   s      If you want microseconds  you need to change the export string and cast to float like  return float now strftime   s  f

Simple  standard library only  Gives timezone-aware datetime  unlike datetime utcnow    from datetime import datetime timezone now utc   datetime now timezone utc

Try this code that uses datetime utcnow     from datetime import datetime datetime utcnow     For your purposes when you need to calculate an amount of time spent between two dates all that you need is to substract end and start dates  The results of such substraction is a timedelta object   From the python docs   class datetime timedelta  days   seconds   microseconds   milliseconds   minutes   hours   weeks           And this means that by default you can get any of the fields mentioned in it s definition -  days  seconds  microseconds  milliseconds  minutes  hours  weeks  Also timedelta instance has total seconds   method that      Return the total number of seconds contained in the duration    Equivalent to  td microseconds    td seconds   td days   24   3600      10 6    10 6 computed with true division enabled
