Green Day Fucked My Stereo

I bought a new stereo, one Saturday, as you do. And after taking it home, messing with my new knobs for a bit, I played the first Green Day album.
20 minutes later I set the clock to 15:26 - because, like, that was the time. 6 hours, some misbehave work and a bit of a session down the line and my brand spanking new sony stereo helpfully tells me that the time is ... 15:26. Did time stop for six hours? Or did Green Day FUCK my stereo ? Readers we leave you to decide.
