Pakistan Standard Time (Urdu : پاکستان معیاری وقت, abbreviated as PKT) is UTC+05:00 hours ahead of Coordinated Universal Time. The time zone is in use during standard time in Asia.
Pakistan had been following UTC+05:30 since 1907 (during the British Raj) and continued using it after independence in 1947. On 15 September 1951, following the findings of mathematician Mahmood Anwar, two time zones were introduced. Karachi Time (KART) was introduced in West Pakistan by adjusting 30 minutes off UTC+05:30 to UTC+05:00, while Dacca Time (DACT) was introduced in East Pakistan by subtracting 30 minutes off UTC+06:30 to UTC+06:00. The changes were made effective on 30, September 1951.PKT is measured in Gilgit, near the village of Naltar. In 1971, Karachi Time was renamed to Pakistan Standard Time.
Daylight saving time is no longer observed in Pakistan.
A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions instead of longitude, because it is convenient for areas in close commercial or other communication to keep the same time.
Daylight saving time (DST), also daylight savings time or daylight time and summer time, is the practice of advancing clocks during summer months so that darkness falls later each day according to the clock. A common implementation of DST is to set clocks forward by one hour in the spring and set clocks back by one hour in autumn to return to standard time. In other words, there is one 23-hour day in late winter or early spring and one 25-hour day in the fall.
Japan Standard Time is the standard time zone in Japan, 9 hours ahead of UTC. There is no daylight saving time, though its introduction has been debated several times. During World War II, it was often called Tokyo Standard Time.
Indian Standard Time (IST) is the time zone observed throughout India, with a time offset of UTC+05:30. India does not observe daylight saving time or other seasonal adjustments. In military and aviation time IST is designated E* ("Echo-Star").
The Hawaii–Aleutian Time Zone observes Hawaii–Aleutian Standard Time (HST), by subtracting ten hours from Coordinated Universal Time (UTC−10:00). The clock time in this zone is based on the mean solar time of the 150th meridian west of the Greenwich Observatory.
Time in New Zealand is divided by law into two standard time zones. The main islands use New Zealand Standard Time (NZST), 12 hours in advance of Coordinated Universal Time (UTC) / military M (Mike), while the outlying Chatham Islands use Chatham Standard Time (CHAST), 12 hours 45 minutes in advance of UTC / military M^ (Mike-Three).
UTC+05:00 is an identifier for a time offset from UTC of +05:00. This time is used in:
Australia uses three main time zones: Australian Western Standard Time, Australian Central Standard Time, and Australian Eastern Standard Time. Time is regulated by the individual state governments, some of which observe daylight saving time (DST). Australia's external territories observe different time zones.
There are eleven time zones in Russia, which currently observe times ranging from UTC+02:00 to UTC+12:00. Daylight saving time is not used in Russia.
Canada is divided into six time zones, based on proposals by Scottish Canadian railway engineer Sir Sandford Fleming, who pioneered the use of the 24-hour clock, the world's time zone system, and a standard prime meridian. Most of Canada operates on standard time from the first Sunday in November to the second Sunday in March and daylight saving time the rest of the year.
Time in Chile is divided into three time zones. Most of Continental Chile uses the time offset UTC−04:00 in winter time and UTC−03:00 in summer time, while the Magallanes and Chilean Antarctica region uses the time offset UTC-03:00 the whole year. Additionally, Easter Island uses the time offset UTC−06:00 in winter time and UTC−05:00 in summer time
The UTC offset is the difference in hours and minutes from Coordinated Universal Time (UTC) for a particular place and date. It is generally shown in the format ±[hh]:[mm], ±[hh][mm], or ±[hh]. So if the time being described is one hour ahead of UTC, the UTC offset would be "+01:00", "+0100", or simply "+01".
Iran Standard Time (IRST) or Iran Time (IT) is the time zone used in Iran. Iran uses a UTC offset UTC+03:30. IRST is defined by the 52.5 degrees east meridian, the same meridian which defines the Iranian calendar and is the official meridian of Iran.
Bangladesh Standard Time (BST) is the time zone of Bangladesh. It is offset six hours ahead of Coordinated Universal Time, and observed as a national standard throughout the country. Bangladesh briefly observed daylight saving time (DST) in 2009 to cope with the ongoing electricity crisis, but in 2010 the decision was cancelled by the government of Bangladesh.
Mexico uses four main time zones since February 2015. Most of the country observes Daylight Saving Time.
The Islamic Republic of Pakistan uses one time zone, which is Pakistan Standard Time (PST). This is UTC+05:00 — that is, five hours ahead of Coordinated Universal Time.
Pakistan has experimented with Daylight Saving Time (DST) a number of times since 2002, shifting local time from UTC+05:00 to UTC+06:00 during various summer periods, having the effect of making Pakistan counter-intuitively half an hour ahead of India during those times, even though India is generally to its east.
Daylight saving time in the Americas is the arrangement in the Americas by which clocks are advanced by one hour in spring and moved back in autumn, to make the most of seasonal daylight. The practice is widespread in North America, with most of Canada, Mexico, and the United States of America participating, but much less so in South America.
As of 2017, daylight saving time is used in the following Asian countries:
Portugal has two time zones and observes daylight saving time. Continental Portugal and Madeira use UTC+00:00, while the Azores use UTC–01:00. Daylight saving time is observed nationwide from the last Sunday in March to the last Sunday in October, so that every year, continental Portugal and Madeira temporarily use UTC+01:00, and the Azores temporarily use UTC+00:00.
