This one. It is in physical terms a unit of angle rather than of time. As such it is quite predictable and constant, being 15 seconds of arc or roughly 7.27220521 × 10-5 radians. It's just that its mapping to SI seconds is not predictable or constant. -- John Cowan http://www.ccil.org/~cowan [email protected] What is the sound of Perl?
