On our old clocks, that would have been impossible, but on digital clocks it happens all the time. Retronyms can signal that the thing double-labeled has become outmoded and obsolete, the superseded exception rather than the rule.

Slang is hot and slang is cool.
Slang is nifty and slang is wicked. Slang is the bee's knees, the cat's whiskers and the cat's pajamas. Slang is far out, groovy and outa sight. Slang is fresh, fly, and phat. Slang is bodacious, ducky, and fantabulous.
