Timeline center date problems

I’m using Timeline 3.4.10 by Daniel Berthereau. In some of my sites, the center-date just doesn’t work. I’ve been entering it as 1950-01-01. I created an empty site with no settings and just the one timeline content block, and this date works fine. So the Timeline module seems to be working. But it doesn’t work on my existing sites. It just defaults to the current date. Is there another site setting that could be screwing up the Timeline?

Hi, It’s hard to say without see it. If it work on a site, there is no reason it doesn’t work on another one. See the readme of the module Timeline.
