How to change date format output in smarty?

Question

Smarty

Hello! There is a meta field with a field fragment on smarty

<meta itemprop="datePublished" content="{$news.date}">

The output is a date in the format: July 31, 2018
And how to bring it to this format? Ydm (2018-07-31)
In pure php, I understand that it can be done through the output of the data() function, but I am not familiar with smarty

That is, it will turn out something like this:

<meta itemprop="datePublished" content="{$news.date|date_format:"%Y-%m-%d"}">
