Nice utilit crate btw :)

Hi @meven , thanks for the suggestion. The reason why the crate now only support i64 is because it is using chrono::Duration, and Duration is only support for i64. Will check how to implement for other data types.

@jk-gan What do you think about float?

0.5.hours()

I like the idea of using float. I can do it later.
