How to search for issues not created in the last 90 days.

In other words, how do I search for issues older than 90 days to see which ones are aged tasks.

The JQL clause created < -90d will find all issues created over 90 days ago. 

The way we write clear English that sentence above does not quite explain the JQL though,

if I were to write the JQL as it looks, it would be more like "show me issues that have a created date less than 90 days ago", and to understand that you have to understand how computers think of dates - they're actually holding a simple counter of "seconds elapsed since a base date", so the larger the number, the later the date/time.  That enables us to use operators like < and > on dates to compare them.
