The https://docs.djangoproject.com/en/2.1/_modules/django/utils/dateparse/
defines:
{{{
standard_duration_re = re.compile(
r'^'
r'(?:(?P<days>-?\d+) (days?, )?)?'
r'((?:(?P<hours>-?\d+):)(?=\d+:\d+))?'
r'(?:(?P<minutes>-?\d+):)?'
r'(?P<seconds>-?\d+)'
r'(?:\.(?P<microseconds>\d{1,6})\d{0,6})?'
r'$'
)
}}}
that doesn't match to negative durations, because of the <hours>
definition final (lookahead) part does not have '-?' in it. The following
will work:
{{{
r'((?:(?P<hours>-?\d+):)(?=-?\d+:-?\d+))?'
}}}
(Thanks to Konstantin Senichev for finding the fix.)
