> This is incorrect... EXACTLY... Yes, I am well aware of that. It was an ill-formed joke, I have a habit of referring to absolutes by using ironic language such as "average" or "standard" or "government issue". I was going to continue tongue-in-cheek about how there are many types of days and UT1 vs. UTC and all the astronomy days, but that would be disingenuous as that is not what I intended, my meaning was strictly to time as understood by the Julianday calculation, which is absolute in dayspan. I realised after your reply that not only was my intent not obvious, it might well be misleading to someone else reading this, and for that reason I apologize and will watch my mouth on this in most of the multiple possible futures. Do not fear though, I am rather decisively on your side of that fence. ;)
