Not this.
1.060 wort at 32 degrees is the same as 1.059 wort at 68. Did you top off? If that's the case then you didn't mix thoroughly and the wort you sampled was the concentrated portion. Otherwise you are Really looking at a few options
1) User error
2) contaminants in the testing apparatus
3) horribly calibrated hydrometer
I would toss your hydrometer in distilled water to make sure it reads 1.000.
After that, my best guess is #2. I don't believe the yeast could drop the gravity that quickly. So having readings that different an hour apart suggests something in the tube altered the density enough for it to read higher than expected. Or it could have been bubbles holding up the hydrometer.
