Open the Time Machine menu in the menu bar, press the Option key on your keyboard, and then choose Verify Backups.
Don't do this when you are in a hurry
Thanks joe, now i see it. Apple hides too much stuff behind the
option key [...the most egregious being 'Convert to ACC...' in iTunes (which lets us convert something that isn't already inside its library).]
Hmm, I wonder if that does anything different than a 'verify disk' using Disk Utility would (other than making the mounting/unmounting of the backup volume a bit easier).
EDIT:
Decided to consult teh google. A quick results scan produced these top hits...
- Why is “Verify Backups†in the Time Machine icon menu disabled?
^ that from August, as yet unresolved... which (in a sense) jives with grelber's Apple support experience.
and...

Seems to be a basic filesystem check (a la Disk Utility).
