I've just started using CourseLab and I find it great. My main goal is to recommend it as a tool to generate SCORM contents.
I've created a very simple course and I've tested it with SCORM® 2004 3rd Edition Conformance Test Suite. Unfortunately, the result is "The Content Package is Non-Conformant".

There's a recurrent error:
SetValue("cmi.interactions.0.timestamp","2008-08-12T11:39:33Z") has been called
ERROR: The SetValue() method call failed
ERROR: Return Value: [ false ]
ERROR: Data Model Element Type Mismatch

I've also tested in Moodle. It works fine but gives an error when reporting "time: PT40.120000000000005S".

Is it a bug of the program or could it be my mistake?
Thanks in advance,
Fernando  

By the way, the same package published for SCORM 1.2 is conformant. I guess it is a bug, then.  

If you want to use SCORM 2004 and you don't need to use the timing then deleting the timestamp component from the Courselab file lms.js will stop the variable being passed.
You could do this for any individual element the API 'knows' about.
