The former currently allows multiple ways of expressing the same thing (WITHIN 5 MINUTES and WITHIN 300 SECONDS), which could be solved by requiring "SECONDS" but allowing X to be an integer or floating point. Switching to a single unit eliminates multiple ways of doing the same thing (as well as expanding the range of possible time scales), which I'm in agreement with.

Affirmative - what Greg says.
