This article from The New York Times via Boing about Toys R Us and others changing digital punch card records of workers hours is a good lesson in the down-side of the digital world:

Experts on compensation say that the illegal doctoring of hourly employees' time records is far more prevalent than most Americans believe. The practice, commonly called shaving time, is easily done and hard to detect — a simple matter of computer keystrokes — and has spurred a growing number of lawsuits and settlements against a wide range of businesses.

It reminded me of a documentary I saw years ago about clocks which said the hour hand was invented in the late medieval era by the church to keep prayers, the second hand by sciencists in the 1700s to measure events being studied but the minute hand was created by industrialists between the two so that they could make a ten-hour day a ten-and-a-half-hour day by slowing the mechanism to steal from the employees. Hence-ish, Billy Blake's line:

The hours of folly are measured by the clock; but of wisdom, no clock can measure.

Some challange to my recollection here. A dictionary of watch and clock related terminology can be found here. I never knew how little I knew.
