Hi, funny thing, one of my user who never posted but was registered something like 3 months ago posted today, and the system put a banner (visible only to the admin I guess):
It’s been a while since we last saw braudpatrice. His last message was 34 years ago.
Really , 34 years ago? 
That notice will be visible to TL2+ depending on what you have set for returning user notice tl
Weird that it’s got 34 years written in it though. 
Thanks, did not know about this setting.
Just as a bonus, there’s a companion one for the new user notice as well - new user notice tl
You can also remove those post notices too using the post wrench if you need to. 
Have you tried changing the language version? Maybe this is a translation error, like if days where translated to ans.
This is the text string I can adapt in French, the {time} variable is used, I do not know by what it is replaced:
Cela faisait un moment que nous n’avions pas vu %{user}. Son dernier message remonte à %{time}.
I googled for the username and found this
So that is incorrect… they did post,
and I think you might have been editing the post date of all topics in “Histoire”.
Oh thanks so much, that’s right, I did change that topic date (and others). Mystery solved 
Hey Patrick,
I know this is not the subject of the thread, but changing the date of posts is dangerous for SEO, if you care about that. Be cautious
Thanks for the links, in my case I posted the topic then changed the date, seconds after the topic was published, for a very much older date, 34 years before ! So because the topic was not on Google index and because the date is not newer but much older, I think I don’t fall under the uses cases discussed in the articles you mention. BTW, I think having the ability to set a topic date before posting would be a bonus. I don’t think it’s possible ?
