How do you change time to 12 hours instead of 24 hours?
I am assuming that you mean "how do you change the time from a 24 hour clock to a twelve hour clock." Just subtract 1200 hours from any time over 1200H. 0000H is midnight. 0100H is 1:00 am etc. up to noon. 1200H is Noon. 1300H is 1:00 pm (ie 1300 - 1200 = 100 = 1:00 pm). 1600H would be 4:00 pm (1600 - 1200 = 400 = 4:00 pm). 2200H is 10:00 pm (2200 - 1200 = 1000 = 10:00 pm).

1.)You can reset your computer clock to "Internet Time" by clicking on the clock in lower right hand corner, follow the links to change date and time settings.
2.)Your cell phone clock is probably within a few seconds of the correct time.
3.)You can get the time signal over short wave radio (weather radio, for example).
5.) The US National Institute of Standards and Technology makes that same time signal available by telephone. The following is quote from the NIST website: "The audio portions of the WWV and WWVH broadcasts can also be heard by telephone. The time announcements are normally delayed by less than 30 ms when using land lines from within the continental United States, and the stability (delay variation) is generally less than 1 ms. When mobile phones are used, the delays are often more than 100 ms due to the multiple access methods used to share cell channels. In rare instances when the telephone connection is made by satellite, the time is delayed by 250 to 500 ms. To hear these broadcasts, dial (303) 499-7111 for WWV (Colorado), and (808) 335-4363for WWVH (Hawaii). Callers are disconnected after 2 minutes. These are not toll-free numbers; callers outside the local calling area are charged for the call at regular long distance rates."

What is 263.1 in hours and minutes?
263.1 minutes in hours and minutes?
263.1 minutes x (1 hour)/(60 minutes) = 4.385 hours = 4 hours and .385 hours x (60 minutes)/(1 hour) = 4 hours and 23.1 minutes
.1 minutes in seconds is: .1 minutes x (60 seconds)/(1 minute) = 6 seconds
So 4 hours 23 minutes and 6 seconds total.

Why does bc years go backwards?
BC means before christ. It is a time (I think incorrectly) denoted as the year the christian prophet, Jesus. Any time before this is said to be 1 year before christ, 2 years before christ etc
It's neither. That's an improper term.
The abbreviations AM and PM stand for Ante Meridiem and Post Meridiem, respectively. The terms ante and post mean before and after. The term meridiem refers to when the sun is at the middle of its arc across the sky.
Nominally the sun is at its meridiem at noon. Since it is *at* its meridiem this is neither before nor after the meridiem. It *is* the meridiem.
Likewise, midnight is neither 12 AM nor 12 PM. It is equally far from both. It is simply 12 midnight.
The military clock is better than the civilian clock for many reasons. One is that eliminates the complexity of specifically accounting for whether a time is before of after midnight. On the military clock noon is read as 1200 hours, and midnight is read as 2400 hours.
This is a variable number. You need to state a start or end date or time.
