jekyll: Missing timezone in metadata date can lead to wrong date in url
Starting with a fresh new Jekyll site with no modifications, I noticed that the first auto-generated post got the wrong page date when served. It looks like a missing timezone in the posts metadata can lead to the generated url being one day off when the time is close enough to midnight.
Metadata of file /_posts/2013-05-09/welcome-to-jekyll.markdown:
---
layout: post
title: "Welcome to Jekyll!"
date: 2013-05-09 22:39:53
categories: jekyll update
---
This leads to the post having url /jekyll/update/2013/05/10/welcome-to-jekyll.html, which can be explained by me being in a timezone with offset +0200.
The url I expected to see was /jekyll/update/2013/05/09/welcome-to-jekyll.html.
Changing or removing the time part of the metadata (or adding timezone info) fixes the problem as expected, but it left me puzzled for a moment.

@parkr I understand how this could cause unexpected results if I’m writing my times assuming UTC +5, and jekyll has a build script that runs when I deploy on a heroku server living in UTC +8, but why ignore the explicit timezone setting in the config file? That seems like a perfectly good way to know what the time should be.
What is the timezone config option used for if not helping jekyll parse dates at build time?
