    The core of this change is to move from moment.js to date-fns.  Why is 
pikaday-time suddenly an issue?
    
    I am concerned about this pikaday dependency.  I would rather see us 
depending on larger, community supported projects like https://momentjs.com/, 
rather than smaller, individual supported projects like @owenmean/pikaday (or 
even your own fork @ruffle1986/pikaday-time).
    
    Not only for continued support from obsolescence, but also because security 
vulnerabilities are all too common and our UI is a large attack surface.  
Larger communities means vulnerabilities are more likely to be uncovered and 
patched. 
    
    I get the technical motivation here.  We want to decrease the load time.  
At the same time, we need to consider the organizations behind our dependencies 
to ensure their long-term viability and support.  
    
     Is there not another way we can tackle the technical challenge here?

> Remove Moment.js and replace with another smaller library.
> Moment.js requires us to import the entire library vs. a few necessary 
> modules.
> Moment.js can prevent bundlers from supporting tree-shaking.
> By removing Moment.js, we can decrease our overall bundle size and prevent 
> issues with tree-shaking in the future.
