Thanks Olaf. Yes, that was my original understanding too. Only that sentence
I quoted from SMIL Animation made me reconsider this.

In SMIL Animation these are largely implementation details but as SVG has
getStartTime some of these details are now visible to the outside world so
we really need test cases to cover this.

There seem to be a few voices suggesting getStartTime return the "previous"
interval as opposed to the proposed erratum. Perhaps the WG will revisit
this issue.

Thanks for the clarification,

Best regards,

Brian
