The easiest and safest way to achieve this is to render the column content only when the spent time or total spent time is > 0:

         value.to_a.map {|a| format_object(a)}.join(" ").html_safe

The current issue where an issue with spent time added with 0 hours cannot be distinguish from an issue with no spent times will remain.

I'm in favour of this change because the view will be cleaner and consistent with estimated time columns.
