    > Why is pikaday-time suddenly an issue?
    
    I agree with you to not use smaller individual projects like 
`pikaday-time`. `pikaday-time` is introduced in the project by @iraghumitra 
almost a year ago.
    The goal wasn't replacing `pikaday-time` with a better well-supported 
library but eliminating `moment.js` because of the aforementioned reasons in 
the description.
    
    > 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).
    
    `moment.js` is a very popular and great library to manipulate date and 
time. 
    
    `date-fns` has the exact same purpose.
    
    `pikaday` is a standalone calendar user interface component.
    
    `pikaday-time` is an extension of `pikaday` with additional fields to 
select time, not just date.
    
    `moment.js` is an optional dependency of `pikaday` (! not `pikaday-time`). 
it works perfectly fine without `moment.js`. But if it is convenient to use 
`pikaday` with `moment`, it's fine then, you can use it by calling `pikaday`'s 
`getMoment` method if needed.
    `pikaday-time` is just a fork of `pikaday` and the author of `pikaday-time` 
made a mistake by setting `moment.js` as a dependency of `pikaday-time` and 
every time we install `pikaday-time` we install `moment.js` too. If `moment.js` 
is installed in the `node_modules` folder `pikaday` will use it therefore it 
will be part of the bundle.
