I want to know how to hide/delete all post times on my forum. For example when you post and it says "Posted x minutes ago."

There is no easy way to do that. You would have to edit your theme templates. And that information appears in lots of templates.

try this, in custom.css add:

time {
  display: none;
}

NOTE: Believe this will remove ALL date/times from everywhere so if want it showing in some areas and not others then as @opentype stated will be a templates job

 Couldn’t you add the postbit / section where the date appears as additional css selector;) ?I‘m not in my office so can’t look it up right now ,but will check it later if nobody else posts it

Possible, didn't look in to it as OP asked for all post times not any specific area

Try in your custom.css

.ipsDataItem_lastPoster time {
   display: none;
}
