1am 2nd Jan 2000
I was asked by a former employer to assess data communication systems for Y2K compliance. I discovered that every single system, all incarnations and all revisions, all over the world would fail at about 1:00 in the morning on the 2nd of January 2000. I also provided the company with a reconfiguration workaround they could implement. I invoiced them for about 30 hours.
The annoying thing for me is that everyone at the company had a university degree, many with PhDs, except me who had left school at 16, when I worked there I was paid a fraction of their salaries. I should have invoiced them for 300 hours.
