For BUG

A sample post 2015-10-11.md is as follows:

---
title: 2015-10-11
date: 2015-10-11 16:08:00
tags:
---

when viewing it on the browser, the title was changed to

Sun Oct 11 2015 00:00:00 GMT+0800 (中国标准时间)

However changing the title to 2015-10-9 in md file would make the post appear normal.

It's possiblely related to how the theme parses the date, which theme are you using? can you provide the theme repo url?

[xiaopxiaop]

I tried two theme, next & landscape, and both had the same issue. So I guess it's not related to theme, but hexo itself.

BTW, when I changed the title from 2015-10-11 to "2015-10-11", the problem was gone.

This is irrelevant to the theme.

The hexo post front-matter must conforms to either JSON or YAML. In YAML, the date type is represented as 2015-12-01. So what you write in the front-matter

title: 2015-10-11
date: 2017-10-03

is equivalent to:

{
   title: new Date("2015-10-11"),
   date: new Date("2017-10-03")
}

The title is converted to string using moment().format, thus is displayed as Sun Oct 11 2015 00:00:00 GMT+0800 (中国标准时间)

If you would like to have the string 2015-10-11 as title, go as

title: '2015-10-11'
date: 2017-10-03

It is interesting to note that hexo g 2015-10-11 does escape the title as string.

Hexo should have check the schema of front matter and throws error. But I'd rather keep things simple and leave it won't fix.
