Date in index page on first build wrong

[dakvid]

When trying (unsuccessfully) to reproduce the error in #58, I noticed an odd issue with the date in the index page - the first time the the page was knitted, the date in index.html was out by a day. Possibly this could be due to my timezone (+1300)?

• I created a new radix blog with a post dated Nov 1. The index page listed it as Oct 31.
• I created a new post dated Nov 4. The index page listed it as Nov 3, but updated the first to Nov 1. (GitHub diff)
• I created a new post dated Nov 3. The index page listed it as Nov 2, but updated the second to Nov 4. (GitHub diff)
• I knitted the third post again, and the index updated it as Nov 3. (GitHub diff)

I'm noticing this issue with distill_article(), as well. Using this metadata:

I get this output:

The result is the same using Sys.Date()
