I don't care so much about the physics, more so about staying within the mathematical rules here, but the physics is important:
I was, again, allegedly, born at 10am (Palestine summer time, UTC + 3). This was reported to me by someone, who asked, and who knows the person that has my birth certificate (Whom I have a terrible relationship with). She just said: Ten am, most likely summer time since it was in May. I'm trying to find out if there is a more precise record with the Palestinian health governing body, and more details about their recording method in 1991 - they are proving hard to reach by phone. My guess is there is at a minimum, a birth registry containing a reasonable estimate of my birth time. If that estimate is written down as 10:00 am, how can I apply ideas of significant digits, precision, and reasonable numerical estimation to arrive at a workable value or range?
Judging where in the world the delivery took place, the provider must have referred to a wall clock. If that is the case, why would a hospital care to adjust the clocks twice a year? Not being certain about the day light savings status, accuracy of the clock used, the recorder's training or mood at the time, I came up with the following:
At worst, the hospital, which was built in 1960, has quartz wall clocks setup sometime between 1960 and 1991, when I was born. Battery life of a double a battery in a typical wall clock according to a result in a google search is 12 months. At worst, the quartz clock used never got adjusted for daylight saving time or when batteries were replaced, ran from sometime between 1960 to 1991 with a +/-20 second accuracy per month, and since, according to another google search result, a typical quartz clock will run for 15 years, that is a loss or gain of right about 20 seconds * 12 months ÷ 60 seconds = 60 minutes. 60 minutes from drifting, 60 minutes due to uncertainty in daylight saving status, and who knows, maybe even another 60 minutes of a range the recorder typically uses (The clock read 9:27 or 10 :45, but the recorder rounded up or down.). So the true value is somewhere between 7:00 and 13:00.
Is there anything in math or physics that dictates how to convert a proposed solution to the above to eastern standard time?
