I am using PHx at the moment, mostly for date manipulation. I have it installed and working, so I thought? I tested a few things with the simple stuff such as :ucase - on to the issues. I installed the ':timesince' modifier. That kills anything I try to use it on. This is true for even built-ins like pub_date. My biggest worry right now is this one.
[+birthday:date=`%m.%d.%Y`+]
That outputs 31.12.1969! And that happens with any date a I throw it. This is being called via Ditto, but cached or not, it does the same thing.
Any ideas?
