Python Dates and Times in Python Dates and Times Timedelta Minute

Timestamp() Got the wrong number of minutes. Expected 1507, got -1507.

Why do i get a negative value?

import datetime

def minutes(time_now, time_tomorrow):
    number_of_seconds = time_now.timestamp() - time_tomorrow.timestamp()
    return round(number_of_seconds / 60)

The challenge states “The first will always be older and the second newer”. So think of the times stored as the number of seconds since 1970. So the second number will be larger. You want second - first.

yeah i saw it after thanks
