#30443 closed New feature (duplicate)

Negative durations are displayed counterintuitively.

Description 

import datetime
from django.utils.duration import duration_string

print(duration_string(datetime.timedelta(seconds=-5)))

This should print -00:00:05 but instead it prints -1 23:59:55 which is interpreted as -1 day, plus 23 hours, plus 59 minutes, plus 55 seconds.

I don't think it's intuitive to support durations that have different signs on the number of days vs hours/minutes/seconds. Note that ISO8601 timestamps just have one sign that applies to all components.
