Which line is Greenwich England time zone?

It's neither. It is 12 Noon.
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.

How many seconds are in a trillion years?
1 trillion years = approx 31557600000000000000. However, the univere did not exist a rillion years ago and, according to current cosmological theories, it will not exist for a trillion years. So the answer is a meaningless exerise in multiplication.
How do you convert from days to seconds?
First, make sure that you are talking about full days and/or fractions of days that have been measured accurately to the nearest second. This may seem unnecessary, but it makes no sense to convert a measurement to seconds if the original measurement is accurate to, say, 'roughly half a day'. This doesn't mean that you already start out knowing the number of seconds.
For example, you may start at exactly 12 noon on Monday, and you want the number of seconds between then and exactly midnight of Thursday night, that week. This time period is exactly 3.5 days of standard time.
Take the number of days (3.5) and multiply by 24 to give the number of hours. 3.5 X 24 = 84 hours. Multiply the number of hours by 60, giving the number of minutes. 84 X 60 = 5040 minutes. Then multiply the number of minutes by 60 to give the number of seconds. 5040 X 60 = 302,400. There are 302,400 seconds in exactly3.5 days.
How many seconds are in 48 hours?
