AstroWeather® Book 2010-Central Time Zone

But his book attracted no attention until long after his death. Scottish-born Canadian Sir Sandford Fleming proposed a worldwide system of time zones in He advocated his system at several international conferences, and is credited with "the initial effort that led to the adoption of the present time meridians". In he specified that his universal day would begin at the anti-meridian of Greenwich th meridian , while conceding that hourly time zones might have some limited local use. He also proposed his system at the International Meridian Conference in October , but it did not adopt his time zones because they were not within its purview.

The conference did adopt a universal day of 24 hours beginning at Greenwich midnight, but specified that it "shall not interfere with the use of local or standard time where desirable". By about , almost all time on Earth was in the form of standard time zones, only some of which used an hourly offset from GMT. Many applied the time at a local astronomical observatory to an entire country, without any reference to GMT.

By , most major countries had adopted hourly time zones. Today, all nations use standard time zones for secular purposes, but they do not all apply the concept as originally conceived. Newfoundland , India, Iran, Afghanistan, Burma, Sri Lanka, the Marquesas , as well as parts of Australia use half-hour deviations from standard time, and some nations, such as Nepal, and some provinces, such as the Chatham Islands of New Zealand, use quarter-hour deviations.

ISO is an international standard that defines methods of representing dates and times in textual form, including specifications for representing time zones. UTC time is also known as "Zulu" time, since "Zulu" is a phonetic alphabet code word for the letter "Z". This numeric representation of time zones is appended to local times in the same way that alphabetic time zone abbreviations or "Z", as above are appended.

The offset from UTC changes with daylight saving time , e. Time zones are often represented by alphabetic abbreviations such as "EST", "WST", and "CST", but these are not part of the international time and date standard ISO and their use as sole designator for a time zone is discouraged.

These examples give the local time at various locations around the world when daylight saving time is not in effect:. Where the adjustment for time zones results in a time at the other side of midnight from UTC, then the date at the location is one day later or earlier. The time-zone adjustment for a specific location may vary because of daylight saving time.

The more familiar term "UTC offset" is used here rather than the term "zone designator" used by the standard.

For example, the New York Stock Exchange opens at These calculations become more complicated near a daylight saving boundary because the UTC offset for zone X is a function of the UTC time. Since the s a nautical standard time system has been in operation for ships on the high seas. Nautical time zones are an ideal form of the terrestrial time zone system.

A nautical date line is implied but not explicitly drawn on time zone maps. It follows the th meridian except where it is interrupted by territorial waters adjacent to land, forming gaps: A ship within the territorial waters of any nation would use that nation's standard time, but would revert to nautical standard time upon leaving its territorial waters.

The captain is permitted to change the ship's clocks at a time of the captain's choice following the ship's entry into another time zone. The captain often chooses midnight. Ships going in shuttle traffic over a time zone border often keep the same time zone all the time, to avoid confusion about work, meal, and shop opening hours. Still the time table for port calls must follow the land time zone.

Ideal time zones, such as nautical time zones, are based on the mean solar time of a particular meridian located in the middle of that zone with boundaries located 7. In practice, zone boundaries are often drawn much farther to the west with often irregular boundaries, and some locations base their time on meridians located far to the east. They were obliged to follow German time during the war, and kept it thereafter. In the mid s the Netherlands, as with other European states, began observing daylight saving summer time.

There is a tendency to draw time zone boundaries far to the west of their meridians. The main reason for this is that similar working day schedules around the world have led to people rising on average at Another reason is that it can allow the more efficient use of sunlight. To make solar noon coincide more with awake time noon i. Many of these locations also use DST , adding yet another nautical time zone to the east. This westernmost area of continental Spain never experiences sunset before Near the summer solstice , Muxia has sunset times after Stockholm has much earlier sunrises, though.

Many countries, and sometimes just certain regions of countries, adopt daylight saving time also known as "Summer Time" during part of the year. This typically involves advancing clocks by an hour near the start of spring and adjusting back in autumn "spring forward", "fall back". Modern DST was first proposed in and was in widespread use in as a wartime measure aimed at conserving coal. Despite controversy , many countries have used it off and on since then; details vary by location and change occasionally.

Most countries around the equator do not observe daylight saving time, since the seasonal difference in sunlight is minimal. Computer operating systems include the necessary support for working with all or almost all possible local times based on the various time zones. Internally, operating systems typically use UTC as their basic time-keeping standard , while providing services for converting local times to and from UTC, and also the ability to automatically change local time conversions at the start and end of daylight saving time in the various time zones.

See the article on daylight saving time for more details on this aspect. Web servers presenting web pages primarily for an audience in a single time zone or a limited range of time zones typically show times as a local time, perhaps with UTC time in brackets. More internationally oriented websites may show times in UTC only or using an arbitrary time zone.

The format is typically based in the W3C Note "datetime".

Email systems and other messaging systems IRC chat , etc. Database records that include a time stamp typically use UTC, especially when the database is part of a system that spans multiple time zones. The use of local time for time-stamping records is not recommended for time zones that implement daylight saving time because once a year there is a one-hour period when local times are ambiguous. Calendar systems nowadays usually tie their time stamps to UTC, and show them differently on computers that are in different time zones.

That works when having telephone or internet meetings. It works less well when travelling, because the calendar events are assumed to take place in the time zone the computer or smartphone was on when creating the event. The event can be shown at the wrong time. For example, if a New Yorker plans to meet someone in Los Angeles at 9 AM, and makes a calendar entry at 9 AM which the computer assumes is New York time , the calendar entry will be at 6 AM if taking the computer's time zone. There is also an option in newer versions of Microsoft Outlook to enter the time zone in which an event will happen, but often not in other calendar systems.

Calendaring software must also deal with daylight saving time DST. If, for political reasons, the begin and end dates of daylight saving time are changed, calendar entries should stay the same in local time, even though they may shift in UTC time. In Google Calendar , calendar events are stored in UTC although shown in local time and might be changed by a time-zone changes, [31] although normal daylight saving start and end are compensated for similar to much other calendar software.

This allows users in multiple timezones to use the same computer, with their respective local times displayed correctly to each user. Time zone information most commonly comes from the IANA time zone database. Windows -based computer systems prior to Windows used local time, but Windows and later can use UTC as the basic system time. Interaction with the user normally uses local time, and application software is able to calculate the time in various zones.

Terminal Services uses the server base time on the Terminal Server and the client time zone information to calculate the time in the session. The other issue for me is more of a personal one. I didn't get much for my personal chart out of either book. As a libra rising with a North Node in libra in the first house ruled by Aries , there is no clear cut answer to the mystery of my North Node. My North Node is in a house ruled by my South Node. So my situation is more of a weird blend of Libra and Aries as opposed to what most people reading this book will encounter.

I think the book will be more useful for doing other people's charts. If you decide to purchase this book, purchase it along with another North Node book or purchase it because you like the work of Elizabeth Spring. But, if this is your only book on the North Node, you might be disappointed with how little is actually covered regarding the North Node. I think the book has value, but perhaps the publisher should have given it a different title to reveal what material is actually discussed in the book. Elizabeth Spring is a thoughtful writer who balances detailed astrological concepts with meanings and interpretations that can be applied to your life, highlighting the path with her personal experience with these concepts.

I first found her when I was trying to understand some family dynamics, trying to understand the north node's role in some very painful family issues, and she kindly responded to my email with a very helpful synapsis of my family dynamics. I bought the book to learn more about the north node and its link to our path of destiny. After reading what pertained to my natal chart, I read the entire book, which gave me a clearer understanding of other family members and my children. I really like this book and it's a permanent part of my astrology library.

I really enjoyed reading this book!

Frequently bought together

The truth is that we are always growing and with astrology there is always something going on with the planets! What I enjoyed about this book is she explains the "possibility" of change. We always have choice in how we go about growth. She explains what we are moving away from--the south node and what we want to aspire to--the north node with creative possibilities for self growth and change.

Found the writing to be engaging. It spoke to the novice as well as to the more experienced astrology students like me. Received the information from a more visceral than intellectual place. Could just feel the rhythm of the cycles described, having experienced many of the outer planet transits covered in the book, Wonderful volume to which I will continue to refer.

I thoroughly enjoyed discovering the correlations between the planets transits and key ages in our lives. I would recommend any woman who has a basic knowledge of astrology and questions her sanity from time to time, to read this. Discovering how the north node interacts with the rest of the natal chart is the main reason I bought the book, and I was not disappointed. A nicely written book about the nodes. Elizabeth gets you thinking about the direction of your life and life purpose.

I like her thought process. One person found this helpful. Excellent book for discovering the purpose and direction of your life path. Even non astrologers could find this of interest. I found that when I studied the charts of family members, the descriptions of their north node was pretty much right on to their personality. A good addition to the library for study books on the North Node. See all 60 reviews. Most recent customer reviews. Published 25 days ago. Published 5 months ago. Published 1 year ago.
