Mary,

Thanks for sending this in. Special thanks for pointing out where the problem 
lay.

Yeah, the parsing of offset time units has always been a problem. 
Unfortunately, the unit-tests didn't cover the use of "ref" is such a 
specification. 

They do now.

I've modified the code to accept "ref" in an offset time-unit. If the change 
passes all the testing, then it'll be out very soon as a new version.
