It will play Weezer's debut album Weezer, starting at such a time that the riff in "Buddy Holly" starts playing at midnight. According to my calculations (though I did not factor in fractional seconds, so I may be slightly off) "My Name Is Jonas" at 11:47:33 pm, so I would recommend you start the project at least before 11:45 pm For the time zone, it's basically the UTC plus or minus numbers thing, without the UTC, and without plus sign, if there is one, but with the minus sign if there is. Remember to convert a :30 or :45 to a decimal .5 or .75 if you live in a half-hour or quarter-hour time zone, and if you live in a southern-hemisphere country that observes daylight saving time, know which number to put.
Start the year the right way. I got the idea from a pin that my sister showed me, but I can't link it since it's another site, and I don't remember her scratch username off the dome; I will put it here if I remember.
