With module boundaries I meant that it could have been that modules work  
only with stuff defined inside of them. I'm really surprised that any time  
or duration type works with all the others. In other words I wouldn't even  
have *tried* to do that and instead rolled my own conversion code. Sorry  
for the ignorance and so on...
