#30434 closed Bug (duplicate)
DurationField silently drops negative sign

Description
When a negative value, such as -00:00:05 is written to a DurationField via the admin interface, the value is silently converted to 00:00:05, dropping the negative.
There is no note in the documentation that this would be expected, and indeed it seems that #27699 was intended to support negative values for DurationFields on SQLite.
I've tried with both SQLite and PostgreSQL database backends.

I think this is a duplicate of #30141 which is fixed (https://github.com/django/django/pull/10999) but doesn't seem to be in the 2.2 branch yet.
