I'm not sure if trend is what you need. Why I'm not sure: because it

Trend works. Maybe it's not what you want, or maybe you've found a bug.

Where does the documentation tell you to combine rates and time?
Print one or the other, and it should work.

Keep in mind that printing vdef timestamps isn't as mature as the
rest of rrdtool yet.
