hyde: TypeError: can't compare offset-naive and offset-aware datetimes

Hi,

I’m running into strange problems with the created: metadata. I started describing the problem here. I’m using the hyde.ext.plugins.git.GitDatesPlugin, Hyde 0.8.4, Python 2.7.2.

In my site.yaml, I have set created: git. If that’s the only place where I set the created metadata, everything works fine, with the datestamp coming from git. However, there’s cases where I want to manually set the created to some other timestamp. But as soon as I enter the line created: !!timestamp '2012-01-05 17:20:20 +01:00' into one of my source documents, the site generation fails:

Traceback (most recent call last):

    reverse=reverse)
TypeError: can't compare offset-naive and offset-aware datetimes

This also happens when I change the line to created: !!timestamp '2012-01-05 17:20:20'.

I’m at a loss here – what’s going wrong? Any help is greatly appreciated!

I’m having the same issue, when trying to overwrite creation and modified dates in single posts. My site.yaml also uses my created: git and modified: git During site generation I get the error as stated above while processing sorter.py: TypeError: can’t compare offset-naive and offset-aware datetimes

A work around that worked for me, ist to remove the timezone from the parsed git timestamp by adding created = created.replace(tzinfo=None) Line 52 and modified = modified.replace(tzinfo=None) Line 55

However this is not a real fix because the timezone offset is lost. I would prefer a solution which parses !!timestamp ‘2012-11-07 15:08:00 +01:00’ correctly (including the tz offset).
