How do I convert timestamp to string in Liquid?

I'm migrating my si开发者_运维百科te from Drupal to Jekyll. In the YAML Front Matter of each post, I have the timestamp it was created.

{{ page.created }} => 1287199856

In Liquid, how do I convert that to:

2010-10-15 23:30:56 -0400

I am not sure, but hope this works

Page Created {{ page.created | date: "%F %H:%M:%S %z" }}
