With $sun_visible_change.long_form I always get 0 minutes, 0 seconds.
I've now figured out the reason for this:
weewx.conf:
[StdReport]
[[Defaults]]
[[[Units]]]
[[[[Groups]]]]
group_deltatime = hour

With this setting, I get the correct display for sunshine duration and rainfall duration in hours
but not for $sun_visible_change.long_form.
How do I get the correct data for $sun_visible_change.long_form ?

Thank you! Turns out, this triggers a bug. See issue #1009. Fix in commit 153c74e.

Is there any particular reason why you are specifying that delta times should be in hours? That's not normally something a user cares about.

Graphic with delta_time = hour

and graphic where the user has not set delta_time = hour

I think the representation with delta_time = hour is clearer

OK, thanks. A good reason!

Werner - can you share your configuration for the Sunshine and Precipitation duration tables ? I'd like to add that to my setup here.

I looked into the definition of class ValueTuple in units.py. If you think of 2 values of group_time and you subtract them, then the result should have another unit (second instead of unix_epoch) and unit group (group_deltatime instead of group_time). But __sub__ preserves the unit and unit group in this case, too.
