The Hour/Minute/Second arms could be deduplicated as they almost identical across seconds/milli/micro/nano, but the handling of milli/micro/nano isn't as straight forward I guess. Though could be handled with a macro I suppose? Let me know if prefer to try reduce this duplication or if it's fine as is

Using Option::then might make this more concise

Tried applying some refactoring as suggested. Clippy does push for use of Option::then_some so I wonder if its better to use that (even though it eagerly evaluates) or to try force usage of Option::then 🤔
