I have read http://oss.oetiker.ch/rrdtool/doc/rrdfetch.en.html#RESOLUTION_INTERVAL and I'm using -start, -end timestamps aligned to 30. However I can't get rrdtool fetch to give me data with the requested resolution:

AIUI, you can only fetch a resolution that exists - it won't do any consolidation/interpolation to transform from what is stored to an arbitrary resolution. I see this isn't mentioned on that page.
