I'm searching/looking since years for a (preferably) portable (MS)Project GANTT-style like software which can track historical events million years back in time.
I've already contacted several project software developer companies (e.g. SmartSheet, TheTimelineProj, OpenProject, Timeline Studio, and view others) but no one seems to be interessted.
Does somebody know of such an software?
... which is capable of track back in time thousend, hundred thousend and million years back in time and overlaying own time scales for (e.g. Zodiac=Earth precision 25920years, user defined time scales) to track in parallel human history, zodiacs and planet orbits e.g. Pluto orbit = 249years, Halley's Comet orbit 76years, meteorits/comets with several hundred and thousend years orbits.
Any hint will be welcome.
Many thanks in advance.
