Answer 1

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.
