How to determine time format from query in frontmatter?

[ReaderGuy42]

I have a frontmatter template that includes something like Total: 7.9h for tracking books (in this case audiobooks). In a dataview query that includes Total as "Length" I then get the output 7 hours, 54 minutes, 0 ms.

In principle I like the minutes being there (even though in this case they're likely rounded wrong since I didn't actually input it to that degree of accuracy) but the milliseconds are unnecessary. How do I change this?

Thanks :)
