I ran into a similar issue. The problem could be that you are using Date::Manip version 6 syntax, and that you are using a perl older than 5.10. In this case, only Date::Manip version 5 syntax is allowed. So the solution is to upgrade to using a newer perl, such as 5.10, or change the syntax of your code to use version 5 of Date::Manip. See the man pages such as: html/site/lib/Date/Manip/DM5.html html/site/lib/Date/Manip.html gmoore777
