From 1989 to 1994 he acted as editor of the journal Vorzeit-Frühzeit-Gegenwart.
Since 1995, he has worked as a publisher and author under his own publishing company, Mantis-Verlag, and publishing his own journal, Zeitensprünge.
First published in 1991, it hypothesizes a conspiracy by the Holy Roman Emperor Otto III, Pope Sylvester II, and possibly the Byzantine Emperor Constantine VII, to fabricate the Anno Domini dating system retrospectively, in order to place them at the special year of AD 1000, and to rewrite history According to this scenario, the entire Carolingian period, including the figure of Charlemagne, is a fabrication, with a "phantom time" of 297 years (AD 614–911) added to the Early Middle Ages.
The proposal has found no favour among mainstream medievalists. He was active in an association dedicated to Immanuel Velikovsky, catastrophism and historical revisionism, Gesellschaft zur Rekonstruktion der Menschheits- und Naturgeschichte.
Illig continued to publish on the "phantom time hypothesis" until at least 2013.
Also in 2013, he published on an unrelated topic of art history, on German Renaissance master Anton Pilgram, but again proposing revisions to conventional chronology, and arguing for the abolition of the art historical category of Mannerism.
Before focusing on the early medieval period, Illig published various proposals for revised chronologies of prehistory and of Ancient Egypt.
