Hong Kong Time (abbreviation: HKT; Chinese: 香港時間; Jyutping: hoeng1 gong2 si4 gaan3) is the time in Hong Kong, observed at UTC+08:00 all year round.[1] The Hong Kong Observatory is the official timekeeper of the Hong Kong Time.[2] It is indicated as Asia/Hong_Kong in the IANA time zone database.

Time standards

In Hong Kong, Hong Kong Time is defined in the Interpretation and General Clauses Ordinance (Cap 1), Laws of Hong Kong.

Section 67(2) of the Ordinance states that:

"Hong Kong Time" (香港時間) means the time used for general purposes throughout Hong Kong namely, 8 hours, or such other period as may be determined by the Legislative Council by resolution under this subsection or under section 16 of the Oil (Conservation and Control) Ordinance (Cap 264), in advance of Universal Standard Time.[3]

Currently, Hong Kong time is defined as UTC+08:00. The reference in section 67(2) to the Oil (Conservation and Control) Ordinance is actually a power given to the Legislative Council of Hong Kong to change Hong Kong Time for the purposes of conserving oil, i.e. to implement daylight saving time. However, no daylight saving time has been observed since 1979.

The Hong Kong Time was first set to

Timekeeping

Radio Hong Kong in 1922, the importance of the time ball decreased. It was decommissioned on 30 June 1933.[2]

During the

Second World War, the equatorial mount and transit circle were lost. After the war, a pendulum clock was installed and regulated by radio time signals from other timekeeping centres. Timing accuracy gradually improved from the daily engineering tolerance
of a few seconds to one-fifth of a second.

In 1966, the pendulum clock in the

timing system. In the same year, the Royal Observatory started to broadcast the time directly with a 6-pip time signal on 95 MHz. This continued until 16 September 1989.

In 1980, the Royal Observatory adopted a timing system based on a

Japan's Communications Research Laboratory. In 1994, the atomic clock was replaced with a newer model.[2]

Current Hong Kong Time can be obtained from the Observatory's Network Time Server Archived 2014-03-14 at the Wayback Machine.

Daylight Saving

Hong Kong adopted daylight saving measures in 1941. However, the practice eventually declined in popularity and was eliminated after 1979.[5]
