Not a bad idea, however you may encounter problems of losing data in these 2 areas: 1. As processors get faster, the difference in execution time shortens and it can be possible to generate the same key during the same millisecond. Adding a NAP 1 in my simulated testing eliminated the duplicates. On one implementation of Pick (Altos?) I recall the resolution of the system(12) function was only a second. 2. At least one time a year (in my timezone) the clock is turned back one hour and it would be possible to overwrite existing keys during that hour. -Troy ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
