Educational Savings for Your Kids

It’s like the one I have. It’s an alarm clock in which the default is set to 12:00 AM or midnight when first plugging it up. The minute changing to me was thought to be constant, when I had no other clock or watch to compare it too. I believe I had a Mickey Mouse clock on the wall but it was too far for my eyes to compare it too, but the minute changes aren’t constant on the digital clock. It contains a Snooze button, a radio, has a button to adjust the hour, minute, which can also reset the second as well because just simply setting the hour won’t affect the second, but the minute will, a wake button which can be used for setting the alarm, and a sleep button which tells you how many minutes it’ll go to sleep. I used to think it was some sort of spell to put you to sleep but I was wrong. My digital clock is at least 12 years old or 4,529 days old or 4,541 sidereal days. Since all the clocks use solar days or solar time, at least 108,696 hours, 6,521,760 minutes, or 391,305,600 seconds have elapsed on it if we ignore the power outages or Daylight Savings changes. Otherwise 108,984 hours, 6,539,040 minutes, or 392,342,400 seconds would’ve elapsed on it if it was a sidereal clock. I received this for my 7th birthday as a birthday present from my dad but what was the earliest I could’ve received it? I’m going to make a calculation soon on how long it takes for the second to get off but I need to know two things at once in order for me to easily do this.
