Something that pops up in #inspircd is that people don't understand the meaning of time for ircds. There should be a page we can redirect those people to, which explains some basics about it and what to do to fix system times and the like.
This issue is merely a reminder for myself, someone else may pick this up and write something.
We already have some documentation on this but it is fairly useless.
That's why this is an issue ;)
