Standard C Date/Time Library: Programming the World's Calendars and Clocks Review

I purchased this book out of interest, but then, as always, there comes a time when you reach for a reference book to help out when you need something coded. Well, that's what I did, and unfortunately the book has basic errors in its Julian to Gregorian conversion routine. Minor, I know, but this book is billed as "the Y2K buster" to get on the bandwagon, but the supplied (tested! hah!) routines don't actually work.I went to the support web site to look up or report this errata. It's gone. Unforgivable. The correct algorithm is available from (the U.S. Naval Observatory's website). The transcription error from this algorithm in Fortran to C is minor, but enough to get me irate. A book that is sold on accuracy and Y2K busting should get dates right. You'd have thought that given a function and it's inverse, that the author would have checked that f(f^-1(x)) == x and f^-1(f(x)) == x. But no...Apart from that, you'll never use many of the other calendric functions. My faith in this tome is severly shaken.
