When are we in true time? Summer or winter?

I agree with the second answer (posted by tmfbitu) but I know what you mean so I'll answer.

We put the clocks back in Autumn and forward in Spring. It's British Summer Time in the Summer (or Daylight Savings Time if you're in the U.S.) and Greenwich Mean Time in the Winter (or of course whichever time zone you are in).

We are due to end B.S.T. (or D.S.T.) very soon.

Neither. Real time for each one of us is our local time, noon when the Sun is on the meridian. However that caused chaos when the railroads first started crisscrossing the world, so Sanford Fleming invented standard time zones, which gradually were adopted around the world. This put fairly large chunks of the population on the same time, and made life easier for railroad excecutives (of which Fleming was one). Then during World War I, somebody got the screwball notion of putting the clocks an hour ahead in the summertime, calling it "Daylight Saving Time" (though I've never figured out how it's supposed to save daylight), and most of us have been doing that ever since. From time to time other screwballs (most recently George W. Bush) tinker with the dates we switch back and forth, which really has no effect other than to confuse people even more. Astronomers, for the most part, ignore all this chaos and use something called Coordinated Universal Time, which is pretty close to Greenwich Mean Time, which was the original standard time established in the 17th century using the local time of the Royal Greenwich Observatory, at longitude 0° 0' 0" in England.

Time and clocks are a man made construction.

Summer is "daylight savings time " and winter time is standard time.

I am so happy I live in a state that does not reset its clocks !!!!

Hope that answers your question.

There is no such thing as "real time". In the US there is "standard time" and "daylight time". Like PDT (Pacific Daylight Time) and PST (Pacific Standard Time). Daylight time is used in summer and standard time is used in winter.

Time is completely relative and kind of meaningless in itself; we all agree to count the seconds, minutes, hours, etc. according to the same (arbitrary) schedule. There is no "real" time.

Dont know which one is a true time!

But you have asked the answer at the right time!

Winter is true time.

there's 365.4 days in a year, why we have a leap year. do not know what happened before a leap year so i have worked the time and date out
