Ok, I know this sounds unbelievable but its exactly what is happening here. I'm running a script that calls this class which creates a PDF document on the fly, and everything was working perfectly.

Working late at night surprised me when an error that I never saw before appeared on my browser:

Fatal error: PDFlib error: Beta expired - retrieve new version from www.pdflib.com in c:\www\htdocs\boleto.pessoal.org\docs\include\boletos\class.pdf.php on line 52

I changed my internal Windows clock to May 1st and the script started working again. Is this a known problem ? It seems kinda ridiculous to have a time limit to use a PHP extension.

That line 52 is the line that contains '$pdf = pdf_new();'. I'm not sure if this happens on every operating system, but it is still a serious problem.
