Fix timedelta precision by importing attotimedelta

Browse Source 
total_seconds() method from Python's datetime class outputs a Float
precision number which for some numbers multiplied by 10^n gives wrong
values.
total_seconds() method from attotime class wraps a native timedelta
object and outputs a Decimal precision number which fixes this issue.
