I need to not display seconds in TimeDelta widget.
I try to look at converter parameter, but but don’t find the way how to remove seconds.
If I remove ‘s’ from converter dictionary I get error:

I found solution.
instead of changing format, I can round to minutes on input, and make migration for existing data.
```
@fields.depends('time')
def on_change_production_time(self):
self.time = datetime.timedelta(minutes=self.time.total_seconds() // 60)
```
