Description
duration_string() formats timedeltas like this:
duration_string(timedelta(hours=1)) '01:00:00'
Given a negative hour, I would expect duration_string() to return something like "-01:00:00". Instead, you get this:
duration_string(timedelta(hours=-1)) '-1 23:00:00'
Note:
See TracTickets
for help on using tickets.
The behavior seems consistent with
str(timedelta(hours=-1))
which gives'-1 day, 23:00:00'
. See Python's docs that explains normalization of negative values.
