Duration zero is not displayed

[Alexgar24]

I've been trying to manage my time using Obsidian and Dataview. First and foremost, thank you for the incredible work; the plugin is fantastic.

I'd like to compute a delta-time by comparing a target duration with an actual duration. To achieve this, I subtract two duration-type values, like: dur("1 hour") - dur("65 minutes"). Thanks to @blacksmithgu, the operation can now display negative numbers. However, when the result is zero, nothing is displayed. I understand that determining what to show can be challenging, but it's counterintuitive to infer that an empty field means the calculation yielded zero.

Thank you!

This can be easily solved by using function durationformat.
