RHElements Datetime Element

This RHElement enables developers to get a lot of the features from the Intl Object just by using attributes to set the format of the date and time they'd like to display.

Usage

Just the date: January 2, 2006

<rh-datetime
  datetime="Mon Jan 2 15:04:05 EST 2006"
  type="local"
  day="numeric"
  month="long"
  year="numeric">
  Mon Jan 2 15:04:05 EST 2006
</rh-datetime>

With time: Monday, Jan 02, 2006, 3:04:05 PM

Code style

Datetime (and all RHElements) use Prettier to auto-format JS and JSON. The style rules get applied when you commit a change. If you choose to, you can integrate your editor with Prettier to have the style rules applied on every save.
