# What time is it... Really?

## 61 posts in this topic

The real question is 'if i turn my clock back from 2am to 1am, when do I stop, I mean when does it become 2:01'?

Don't forget to change your clocks :)

Time is an illusion :shifty:

Time is a human invention. So question is invalid.

The units of time (hours, minutes, seconds, etc.) are a human invention, but time itself is a fundamental aspect of the universe.

Its time to kick ass and chew bubble gum.

If the earth turn around self is integer times corresponding the time around sun.

It will no need to set "leap year"

whatever it is , its convention :)

Time is a completely human invention, there's nothing fundamental about it. What people think of as a 'fundamental aspect of the universe' is actually entropy

True. But the original question is still invalid, because putting a specific label on the amount of time passed since event x is always introducing an artificial, meaningless element.

To make up for this lost time, we of course have added the idea of a "leap year" in which every 4 years we add an extra day. But if you do the math, that "leap year" does not fully account for every last second & as time continues to add... Those seconds become minutes, hours, days.... And of course, what about all the years before the calender included a "leap year"....

Err - do you not know why we have a leap year?

We say there are 365 days in the year and by this we mean that it takes the earth 365 days to make its annual trip around the sun. Actually, though, it takes the earth 365-1/4 days to make this trip. This means that every year we gain one-fourth of a day and every four years we gain one full day.

If we did nothing about this, our calendar would move backward one full day every four years relative to our seasons. To keep this from happening, we capture the extra day every four years and put it into our smallest month, February.

Something like that.

^ I wonder what year & daily time Humans would use, if perhaps Mars was colonized ... ;)

It's Howdy Doody Time!

The de facto calender is the Gregorian calender. As of this post, the current time is 5:10pm Sunday (EST).

Does it really matters what time it really is, or in what year are we on? Life goes on, without any hitch on my side.

OK, I'd like to see you get rid of time.

As I was walking down the street one day

A man came up to me and asked me what

The time was that was on my watch, yeah...And I said

(I don't) Does anybody really know what time it is

(Care) Does anybody really care (about time)

If so I can't imagine why (Oh no, no)

We've all got time enough to cry

And I was walking down the street one day

A pretty lady looked at me

(I don't) Does anybody really know what time it is

(Care) Does anybody really care (about time)

If so I can't imagine why (Oh no, no)

We've all got time enough to cry

And I was walking down the street one day

Being pushed and shoved by people trying to

Beat the clock, oh, no I just don't know

I don't know, and I said, yes I said

(Background:)

People runnin' everywhere

Don't know where to go

Don't know where I am

Can't see past the next step

Don't have time to think past the last mile

Have no time to look around

Just run around, run around and think why

(I don't) Does anybody really know what time it is

(Care) Does anybody really care (about time)

If so I can't imagine why (Oh no, no)

We've all got time enough to die

Everybody's working (I don't) I don't care (About time)

About time (Oh no, no) I don't care

according to new earth time clock - 354º45'00"

As a species we invented time. If we choose to change it around, move it, reverse it or whatever it's our doing as this has no effect on anyone/thing else.

No, we didn't. We invented the measurement units only.

Sure, we defined arbitrary lengths of time and made up words for those lengths of time, but there's nothing we can do to affect time itself. We can't stop it, slow it down, speed it up, reverse it, etc. It's a property of the universe and can't be changed.

Our universe would be pretty much useless without time.

That's not entirely true. Time can be influenced by traveling at high speeds and near heavy objects. It's not a constant that's everywhere the same. In fact our GPS satellites are suffering from this effect and the onboard computers are designed to compensate for that very effect.

but that is just a property of time itself - i.e. it will go slower for things moving faster, but we cant slow it down even more or not slow it down as much if something is travelling at a constant speed

Exactly. It's like 2+2 is 4, but 2+3 is 5. Change the variables, and you change the outcome. Even when your variables are arbitrary (for example, I say 2+3 is 7 because when I say 3 I really mean the value 5), you can't change the underlying rules behind those arbitrary values.
