# Thread: Metric Time

Is this not obvious?
Apparently not, since you're incorrect. Time passes at different rates according to different factors involved in your motion, mass, etc. Time passes differently under different strengths of gravitational force.

Time does describe a physical system, in the sense that we can use it to measure change, and if it is involved in measurement, it has a unit. However, most of the disagreements aren't really about time, but about calendar and dates. Dates make sense because from year to year, every local region can find comparison from the date of one day on one year, to the following date of another year, in terms of climate, responsibilities, tasks, etc. It is easy to compare May vs. December, it is not so easy to compare 365.47 vs. 1048.63, in those terms.

Everything we do here is dictated by the year cycle. It makes sense to catalogue the passage of time using that cycle to maintain consistency.

Once we are free of that cycle, it obviously becomes a less important thing to consider.

You see, that's actually another reason it should be changed or removed from the standard calender. I actually find it mildly offensive that I have religion thrown in my face every time someone talks about what day it is. So it's not only arbitrary, poorly labeled, and difficult to keep track of, it's rather offensive to people who don't share the religion of the people who invented it. It's one thing for religious people to want it, but why should the rest of us be subjected to it when we're trying to figure out when something happens?

Hmm... everything else can be justified based on how people had to tell time in the past, in my mind, but I firmly believe that the week is a truly awful unit of time.
Actually, I read some interesting research about why the week is an excellent unit of time. We as humans have a body clock that doesn't match the length of our days (it's an argument sometimes used for why we might be alien to the planet, although let's not go into that here!). In any case, this means that each day we are forced to keep to a schedule we, typically, move out of synch by up to an hour. After 5 or 6 days, the relaxing plus chance - hopefully- to sleep late fix that imbalance.

So, the week as a unit might be officially religious in origin, but to me it seems more likely that religious texts were already enshrining something intrinsic to the human experience on a 24 hour day planet. Put us on a 25 hour day planet and give us the extra hour to sleep, and we shouldnt need to use weeks as a unit (although it's still nice to have leisure time, right?)

Which in turn will unconsciously lead to increased support for the space program.
You're asking for people on earth to stop using earth terms?

People are going to continue using 24 hour days even in space because there's no incentive to switch to something else. There's no need to redefine seconds, minutes, hours just because you're no longer bound to those cycles. I mean sure, you could set up 10 hours with 100 minutes or something, cut into different durations than our current hours and minutes, but why?

What you may see in the far far far future when another planet is colonized that they will set up their own system as the earth system is then out of synch with their days. In this case the old system will still persist because you can't standardize such a thing. Earth may have 10 metric hours and Planet J might have 15.23 metric hours. They still don't match, you can't unify them. It will require a system of conversions to synch it all up.

Not relative to the individual, though. For a given individual, time is always experienced at the same rate.

What do motion and mass have to do with time? That only changes the way we end up measuring time relative to something, not the consequences of it's passing. Everything is happening everywhere simultaneously, it just SEEMS to be happening at different speeds in different places because of distortion.

But regions, climate, movement... ARGH. That doesn't have anything to do with it...

I really can't wrap my head around the way most other people think. Other people's thoughts are all warped by the physical world, the way the measuring tape reacts instead of the object of measure, and the human experience with it's associated tendencies and insecurities... they don't understand anything clearly.

Changes in motion and mass also equate to changes in the passage of time. It's why particles in accelerators decay far slower and "live longer," their speed and mass change the way they move through time.

Also, with the bolded, no. There is no standard, absolute vantage point of experience that is any more or less correct than another. If you see something happen at a different time than your friend who is on a different relative plane of experience, neither of you is wrong. The event did happen at different times.

This is becoming a physics discussion, and I know that's not really the point of your thread, so I'll stop.

And I cannot wrap my head around why you want to institute a change to how time is labeled and catalogued when that change would be less relevant and applicable to observation.

Actually, that's interesting... I'll probably go and research that later on to see if I can make sense out of time.

Well, because I consider simplicity, compactness, and consistency in defining a specific point more relevant than observation. Basically, I believe the physical world and what we can observe in it is largely irrelevant except for the concepts we can derive/extract from it, and the specific, present nature of things shouldn't be allowed to distort a person's thoughts about other potential natures things might have.

Basically... I don't see anything really trustworthy in external, local, observable reality, and find the fact that others do, somewhat strange and repulsive.

I do agree with you that the 60's are a bit arbitrary. I'd could live with base 10 units so that I could use the in built calculator (fingers)

Yeah, exactly!

I don't know, maybe people will get it eventually, after they get into space and a few generations pass without having lived mostly on a planet orbiting a star. They're going to have to be exposed to an environment where it's apparent that it's irrelevant to understand the concept that it is so. Oh, well.

This thread probably removes much doubt about whether I'm an N-dominant type, huh?

9. This thread is cute.

10. When I first learned the metric system in school; I wondered why time was left out, and later figured a metric second would be 1/100,000th of a day, or .864 seconds.
What the site in the link did not consider for a prefix for hundred thousandth was "decimilli-". (Though one person argued the SI would never accept that).
My interest was sparked off when I worked the 2000 Census, and saw for the first time the decimalized hour, (where :30 becomes .5; :15 beomes .25, etc), and figured they should go all the way for the whole day.

When I looked it up online, I found the site http://www.decimaltime.hynes.net and joined its forum, but it seems to be down for good now.

I also figured that the week and month could be replaced, but not the year because of the seasons.
The week would be difficult, because we are so used to the 7 day rhythm. How would we even distribute the work days and weekend? Not two days off, eight says on? Longer weekend? Four days off, six days on? Or spread the off says? Like 3/3/4 or something?
And most of the religions would never give up the 7 day week, because that's tied to divine Creation.

But the divisions of the day should be considered.
