分析和测试时间的Common Lisp库

This project has moved to github: https://github.com/wmannis/cl-period This library is partly inspired by Perl"s Time::Period library, but now owes more to the time classes of cfengine. There was a Ruby Quiz (#114) to do something similar, but they called it a time "window." It"s intended for use in long-running — or frequently running — programs whose action may be limited to particular time frames. For example, if a program is empowered to send me a page I might want to tell it only to do so during work hours. The library supports two notations for time periods, one lispy, one modeled on cfengine"s classes. First release (0.01 - you gotta start somewhere) April 18th, 2008. See the documentation.
