The Y-Zero-K Problem

The Y-Zero-K Problem Translated from a recently discovered Latin scroll dated 2BC Dear Cassius: Are you still working on the Y zero K problem? This change from BC to AD is giving us many headaches; there is not much time left. I don't know how citizens will cope with working the wrong way around. Having been working happily downwards forever, now we have to start thinking upwards. You would think that someone would have thought of this earlier and not left it to us to sort it out at the last minute. I spoke to Caesar the other evening. He was livid that Julius hadn't done something about it when he was working out the calendar. He said he could see why Brutus turned nasty. We called in Consultus, but he simply said that continuing downwards using minus BC won't work and as usual charged a fortune for doing nothing useful. Surely, we will not have to throw out all our hardware and start again? Macrohard will make yet another fortune out of this, I suppose. The money lenders are paranoid of course! They have been told that all usury rates will invert, and they will have to pay their clients to take out loans. It is an ill wind...
. As for myself, I just cannot see how the sand in an hourglass will flow upwards. We have heard that there are three wise men in the East who have been working on the problem, but unfortunately they won't arrive until it's all over. I have heard that there are plans to stable all horses at midnight at the turn of the year as there are fears that they will stop and try to run backwards, causing immense damage to chariots and possible loss of life. Some say the world will cease to exist at the moment of transition. Anyway, we are still continuing to work on this acursed Y zero K problem. I will send you a parchment if anything further develops. If you have any ideas please let me know, Plutonius Sent by Marina
