As I've developed a ticket rule on my K1000 Applicance to automatically close a ticket once it has been created if a certain criteria is not met on the parent ticket of the process, the TIME OPEN field automatically fills with an odd time.
A little math leads that time, which today is -15840 days, to January 1st, 1970. The first day of Unix Time.
Also known as the big bang of computer time ;)
Although it looks absolutely ugly on our ticket layout, was definitely learnt something in the process!
