The problem comes when we try to fit in behaviors into our model, rather than have models to explain behavior. Sun does what it wants to do - Just because scientists observed something periodic, does not require the Sun to behave appropriately. For e.g., fitting employees performance to a Bell Curve (normalization curve) - Here we take data and fudge it to fit into the model for the sake of convenience of management. It might be of scientific interest to see why this happened, though. Just let the Sun be! Sriram

I tried Help Desk Pilot for some time - There used to be a free version for limited users. The support is also pretty good. I am not sure if the free version is still around. It's worth checking out http://www.helpdeskpilot.com/

But isn't time measurement relative and personal in a Einsteinian Universe? :-) And, I was told time exists only in the mind. Also, time flows from a low entropy to a high entropy state. I am also curious how time is related to rate of change of entropy. Will it either speed up or slowdown with change in entropy? In the end, I'd like to measure time only by the way I see it (I don't wear a watch!) I was once imagining how God is able to know the past, present and the future..
