Date not observed for video posts

[danst0]

Just for testing I executed those commands directly after one another:

post_id = client.create_text("xxx", state="published", date="16.1.2014",
                                                 title=caption, body="Hallo", tags=tags, format=html_or_markdown)
post_id = client.create_video("xxx", state="published", date="16.1.2014",
                                                     caption=caption, tags=tags, data=tumblr_video, format=html_or_markdown)

The first one creates a text entry with the correct date.
The second creates a video with the current date...

Any hints why?
