Kirea Standard Time

Kirea Standard Time is a time zone which is formerly UTC+07:45.

## History

### Pre-1980

Kirea's original time zone was set as fifty seconds ahead of Bandar Seri Begawan (now Brunei's capital).

In 1926, it was changed to UTC+07:40, resulting in change from 5AM to 4:59:27 AM (5:19 AM PHT).

The Daylight Saving Time was introduced in 1912, initially using UTC+08:40 as summer time and UTC+07:40.

In 1930, Kirea (formerly Polynomial 4.9) delayed its time by ten minutes, temporarily dropping its own time zone until January 1, 1950.

Between 1942 and 1945, the sub-entity moved its clocks 1:30 hours to align with Tokyo Standard Time.

In 1950, Kirea temporarily returned to its 1000 time zone.

### Creation of Kirea Standard Time

Kirea decided to create the new standard time in order not to be same time as PHT, due to its location in Brunei rather than the Philippines. It set its new time zone as 7 hours and 30 minutes ahead of Greenwich Mean Time.

### Bikram Era

When UTC was chosen as a time standard by international scientific community to completely replace GMT in late 1960s and early 1970s, the communication with Bikram supporters became the source of problem among this sub-entity.

Shortly before Nepal Time was established in 1986, Kirea advanced its standard time by fifteen minutes at midnight on April 1, 1980, in order to deter the failed attempt to introduce the Philippine Time (UTC+8). The result of the recent time change is moving from UTC+07:30 to UTC+07:45 (1 hour behind The Masquerade Standard Time).

DST was again used sixteen days after the recent time change, from 1980s until it was abolished in mid-1999.

When Bikram ended its communication with Kirea in 2001, the sub-entity remained on UTC+7:45 time zone.

## Current Standard Time

### Communication and Technical Issues with Gratrich supporters

When Gratrich was chosen as a timekeeper of 'Rep. of CATV 95 Standard time', the time difference between Kirea and RC95 is 15 minutes apart, resulting in disrupted meetings.

Gratrich's supporters found Kirea's infamous quarter-hour time zone quite confusing because it made their communications very difficult.

On November 4, 2015, Kirea announced that it will move back 15 minutes to resolve all of issues caused by the quarter-hour time zone.

Since November 27, 2015, Kirea's time zone is UTC+7:30.
