Re: [PHP-DEV] [RFC] Duration class

[Holly Schilling]

I don’t want to distract from the core functionality discussed about this, but 
I’ve been working on something that might be a factor. I have a proposal coming 
for Value Structs once 8.6 closes. `Duration` would be a great candidate for 
being a struct instead of a class.
