Eh I prefer Imperial Standard. You can half, quater, third, etc inches and feet, unlike metric.
Sounds like a Machinist.
24 hour clock. No question what time of day you mean.And while we're at it, do away with daylight savings.
I'm retired, don't need no stink clocks, and I especially don't need an alarm clock.
I'm in the USA, I always use the 24hr clock.
I don't need an alarm clock either--except I have two of them, wrapped in fur. They know when 5 am rolls around and then, so do I.
I usually have to wake my fur wrapped alarm clock up when I get up (he's almost 12) and if he has a need and gets me up with a need, he also wants to go back to bed.
It can be a quarter to four, or a quarter after four. Some people say a quarter OF four. But I don't know what that means.
I have no problem with either and get quite frustrated with those that can grasp it's simplicity. But I must admit I get more annoyed at people that cannot understand the equal simplicity of using the clock for directions..."check out that shit at 8:30.....wut?....really dude?
