On the actual news page, it shows up as 9 AM. But on Ditto, it appears as 10 AM.
How can I tell Ditto to go back one hour?
This looks like you have a server time offset in the news section. You can set an offset in the manager in the site configuration section in the site tab close to the end of the page labeled Server offset time. I have never used this, but this is what I think it is for.
Do you have a system offset time set? If so, Ditto will take that into effect when rendering the time in the [+date+] placeholder.
