It's time for a change

EDIT: OK, those of you who picked both "twenty ten" and "two thousand eleven" have some explaining to do.

without resorting to IPA
"twenty" "eleven" -- two discrete units, but the dual unstressed syllables with the same vowel sound (in my dialect at least) between the liminal boundaries come out sounding like a hiccup and trip your tonge; native english speakers don't often find dual unstressed syllables bookended by stressed syllables natural where the unstressed vowel sound is identical or near-identical: "TWEHN-teee eee-LEH-vuhn" is not a natural occurrance in my dialect (speakers contort things so they don't have to use them whenever possible), so it's either slur (TWEHN-tee-LEH-vun) or make it into "TWO THOU-suhnd-eee-LEH-vun".
(Note that the 'eee' in 'eleven' is slightly more midvowel than the "eee" in "twenty", but close enough, in my dialect.)
