Very tense, agitated, ready to explode
Clocks that have to be wound by hand fall into two categories, those that have to be wound every day, and those that have to be wound at longer intervals. Those that have to be wound at longer intervals are usually either 8 day clocks, or 31 day clocks. What it means is that the clock is designed to be wound the same time of the month each month. If you had a 31 day clock, you could wind it on the first of every month and know that it would last to the next month no matter what month it was. 8 day clocks are designed to be wound every 7 days.
A 400 day clock is another term for a torsion clock which is a device that keeps time using a torsion pendulum. It is also known as an anniversary clock.
the clock wanted to be like Michael Jackson
This refers to one particular kind of clock, the 400 day clock made by S. Haller and most typically marketed as an Elgin. Its flawed main spring design can cause the clock to explode when fully wound, and/or when someone is trying to repair it. Search 'German time bomb clock' for more data,
AM stands for ante meridiam (Latin for "before mid-day")
Because it is in the middle of day
A time of the day. If you mean something else, then please be less vague.
its after twelve o clock. afternoon "pm" stands for "post-meridian", which means the Sun has passed the mid-day point in the sky.
'The car was the man's means of getting to work each day.''He used his means of time and skill to bake a cake.'
the little clock gives an indication of the time of day. It is adjustable to any time zone but loses some accuracy at speeds above mach 4
You have to clean and dress the wound on alternate day till the wound heals.
Because, when using "apparent solar time", the length of a "solar day" varies slightly during the year. (This is because the Earth's orbit isn't exactly circular and the Earth's axis is tilted.) "Clock time" is based on an average (or "mean") of these day lengths, called the "mean solar day". So clocks use "mean solar time". (By coincidence, on the date the question was answered (14th April) "apparent solar time" and 'clock' time are synchronised.) There's another reason for apparent solar time being different from clock time. "Clock time" uses time zones. So, over a wide area, the time on a clock equals the "mean solar time" at a particular, defining, longitude.
