Improvements in worldwide communication further increased the need for interacting parties to communicate mutually comprehensible time references to one another.

The problem of differing local times could be solved across larger areas by synchronizing clocks worldwide, but in many places that adopted time would then differ markedly from the solar time to which people were accustomed.

On November 2, , the then British colony of New Zealand officially adopted a standard time to be observed throughout the colony, and was perhaps the first country to do so.

This standard was known as New Zealand Mean Time. Timekeeping on the American railroads in the midth century was somewhat confused.

Some junctions served by several railroads had a clock for each railroad, each showing a different time. Dowd proposed a system of one-hour standard time zones for American railroads about , although he published nothing on the matter at that time and did not consult railroad officials until In he proposed four ideal time zones having north—south borders , the first centered on Washington, D.

For example, the border between its Eastern and Central time zones ran through Detroit , Buffalo , Pittsburgh , Atlanta , and Charleston.

It was inaugurated on Sunday, November 18, , also called "The Day of Two Noons", [7] when each railroad station clock was reset as standard-time noon was reached within each time zone.

The confusion of times came to an end when Standard zone time was formally adopted by the U. Congress in the Standard Time Act of March 19, The first known person to conceive of a worldwide system of time zones was the Italian mathematician Quirico Filopanti.

He introduced the idea in his book Miranda! He proposed 24 hourly time zones, which he called "longitudinal days", the first centred on the meridian of Rome.

He also proposed a universal time to be used in astronomy and telegraphy. 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: 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 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. 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.

While most application software will use the underlying operating system for timezone information, the Java Platform , from version 1.

This database is updated whenever timezone rules change. Oracle provides an updater tool for this purpose. As an alternative to the timezone information bundled with the Java Platform, programmers may choose to use the Joda-Time library.

Java 8 Date Time. There is very little in the way of timezone support for JavaScript. Essentially the programmer has to extract the UTC offset by instantiating a time object, getting a GMT time from it, and differencing the two.

This does not provide a solution for daylight saving variations. The DateTime object in Perl supports all time zones in the Olson DB and includes the ability to get, set and convert between time zones.

This includes the ability to get and set the default script timezone, and DateTime is aware of its own timezone internally. The standard module datetime included with Python stores and operates on the timezone information class tzinfo.

The third party pytz module provides access to the full IANA time zone database. Each Smalltalk dialect comes with its own built-in classes for dates, times and timestamps, only a few of which implement the DateAndTime and Duration classes as specified by the ANSI Smalltalk Standard.

VisualWorks provides a TimeZone class that supports up to two annually recurring offset transitions, which are assumed to apply to all years same behavior as Windows time zones.

Squeak provides a Timezone class that does not support any offset transitions. Dolphin Smalltalk does not support time zones at all. VisualWorks, Squeak, Gemstone, or Dolphin.
