1. 请看两段帖，是1982年用东马时间，非1985年。
2. 时差约30分钟。细节太复杂了，看下面吧！
3. 一个盘的最终决定因素是在于验盘功夫还是时间呢？看倌们、自己决定吧！
注3: 岀生时间(birth time, not day or date)是个參考以方便起盘论命时别差太远。
A. Time Zones in Malaysia Some years ago I created this page based on information from the file asia, which is part of the tz database. After giving a lecture on the Chinese calendar at the Department of History at the National University of Singapore I got in touch with Mok Ly Yng, who has researched this extensively, and corrected some errors in the tz database. I have created a page with the article he sent me. I have kept this page because it gives information about East Malaysia, too. I use the modern terms East and West Malaysia for convenience.
The local mean time in Kuala Lumpur is (6:46:48). West Malaysia used local mean time until 1880, when they changed to Singapore mean time (6:55:24). In 1905 they changed to 7:00, in 1933 to 7:20 and in 1941 to 7:30. During the Japanese occupation, Tokyo time was used, before changing back to 7:30 in 1945. In 1982, they finally changed to 8:00. This was done to create a single time zone for East and West Malaysia. Since the capital and 80% of the population is in West Malaysia, I've always found it strange that the whole country follows East Malaysia's time, but I guess it was a gesture of goodwill towards East Malaysia.

Sabah and Sarawak used local mean time until 1926. They then changed to 7:30. In 1933, when West Malaysia changed to 7:20, they changed to 8:00, with a 20min time change between September 14 and December 14. During the Japanese occupation, Tokyo time was used, before changing back to 8:00, but without the daylight savings time, in 1945. The tz database does not distinguish between Sabah and Sarawak, so I assume that these changes applied to both places.

B. Malaysian Standard TimeFrom Wikipedia, the free encyclopediaJump to: navigation, search Malaysian Standard Time (MST; Malay: Waktu Piawai Malaysia) is a standard time used in Malaysia. It is 8 hours ahead of Greenwich Mean Time and Coordinated Universal Time. The local mean time in Kuala Lumpur was originally +6:46:48 GMT. Peninsular Malaysia used this local mean time until 1880, when they changed to Singapore mean time +6:55:24 GMT. Between the end of the Second World War and the formation of Malaysia in 1963, it was known as British Malayan Standard Time, which was 7.5 hours ahead of Greenwich Mean Time. At 23:30 hrs local time of December 31, 1981, people in Peninsular Malaysia adjusted their clocks and watches ahead by 30 minutes to match the time in use in East Malaysia, which was 00:00 hrs of January 1, 1982. [edit] Time changing chronicles (Peninsular Malaysia) | Period in use | Time offset from GMT | Name of Time (unofficial) | | Until May 31, 1905 | + 6hr 46m 48s | British Malayan Mean Time | | June 1, 1905 - December 31, 1932 | + 7hr 00m 00s | Standard Zone Time | | January 1, 1933 - August 31, 1941 | + 7hr 20m 00s | Daylight Saving Time | | September 1, 1941 - February 15, 1942 | + 7hr 30m 00s | Daylight Saving Time | | February 16, 1942 - September 12, 1945 | + 9hr 00m 00s | Tokyo Standard Time | | September 13, 1945 - December 31, 1981 | + 7hr 30m 00s | Daylight Saving Time/Malaysian Standard Time | | January 1, 1982 - Present | + 8hr 00m 00s | Malaysian Standard Time |
[edit] Time in East MalaysiaThe local mean time in Kuching is +7:21:20 GMT. Sabah and Sarawak used local mean time until 1926. They then changed to +7:30 GMT. In 1933, when West Malaysia changed to +7:20 GMT, they changed to +8:00 GMT, with a 20-minute time change between September 14 and December 14. During the Japanese occupation, Tokyo time (+9:00 GMT) was used, before changing back to +8:00 GMT, but without the daylight saving time, in 1945.

[edit] History - Prior to 1 January 1901 - locations in British Malaya with an Astronomical Observatory would adopt the local mean time based on the Observatory's geographical position. Penang, Malacca and Singapore all had their own observatories; hence, the three Straits Settlements had their respective Local Mean Time, with minutes of differences amongst the three locations.
- 1920 - In 1920, a bill was introduced in the Straits Settlements’ Legislative Council to adopt “Daylight Saving Time” just like in England. The proposed time was 30 min forward of the mean time of the 105th meridian, i.e. 0730 hours ahead of GMT. The reason for proposing this was to allow more leisure time for the labourers after work. This bill was dropped after the first reading.
- 1901 - On 1 January 1901, Singapore's Local Mean Time (Singapore Mean Time) was adopted by the Straits Settlements and the Federated Malay States as the Standard Time. This was introduced because railway, postal and telegraphic services were becoming more common and a single standard time will ease scheduling problems. Singapore was chosen because it was the administrative HQ for the SS and the FMS then.
- 1905 - On 1 June 1905, the mean time of the 105th Meridian (Longitude 105 degrees East) was adopted by the Straits Settlements and the Federated Malay States as the new Standard Time. This decision was made way back in February, 1904. The mean time of the 105th meridian is 7 hours ahead of Greenwich Mean Time (i.e. the Local Mean Time over Greenwich Royal Observatory near London, England). This Standard Time went into effect when the Time Ball on Fort Canning was completed and became operational on the same day.
- 1932 - 12 years after the 1920 introduction of the “Daylight Saving Bill”, the same bill was reintroduced to the Legislative Council. One of the original reasons for dropping the 1920 Bill was the argument that 30 minutes was too much change. Therefore, in 1932, the proposed shift was reduced by 10 minutes, down to 20 minutes ahead of the mean time of the 105th meridian. This was a compromise, which was perceived to be more acceptable to the overly cautious Legislative Council members. After 2 debating sessions, this Bill was passed and became Ordinance No. 21 of 1932. The short title was Daylight Saving Ordinance, 1932. This was to come into force on the first day of January, 1933, and was to be in force during the year 1933.
- 1933 - 1 January 1933, the Daylight Saving Ordinance came into effect on New Year's Day. This Ordinance as passed was in effect for the year 1933 only. Daylight Saving Time was 20 minutes faster than Standard Time, i.e. 0720 hours minutes ahead of GMT.
- 1934-1935 - For the years 1934 and 1935, the Daylight Saving Ordinance, 1932 was extended throughout both years by Gazette Notifications.
- 1935 - In 1935, the Daylight Saving Ordinance, 1932 was amended by Ordinance No. 5 of 1935--The Daylight Saving (Amendment) Ordinance, 1935. The year limit '1933' was removed, turning the ordinance into permanent effect without the need for the Governor to declare any extensions. The time of 0720 hours ahead of GMT became permanent “Standard Time” with this amendment. The Survey Department's 1935 Annual Report advised readers to adjust their clocks appropriately by 20 minutes for the year 1936.
- 1936 - The Daylight Saving Ordinance became Chapter 170 in the 1936 Edition of The Laws of the Straits Settlements.
- 1941 - In 1941, the Daylight Saving Ordinance was amended yet again by Ordinance 33 of 1941. Daylight Saving Time would henceforth be 30 min ahead of the mean time of the 105th meridian (10 min more than the original DST), i.e. 0730 hours ahead of GMT. This came into effect on 1 September 1941. Interesting to note that this was the original DST proposed in 1920 and was met with much opposition then.
- 1942 - 16 February 1942, Japanese formally occupied British Malaya. British Malayan time moved ahead by 1 hour 30 minutes to conform with Tokyo Standard Time, which is 0900 hours ahead of GMT.
- 1945 - 12 September 1945, Japanese formally surrendered in Singapore. British Malayan time reverted to “pre-invasion” standard: 0730 hours ahead of GMT. The exact dates for the change to and from Tokyo Standard Time have not been ascertained yet. The dates given here are based on educated speculation.
[edit] Standardisation of time in MalaysiaMalaysia declared that people in West Malaysia would move their clocks ahead by 30 min to match the time in use in East Malaysia (8 hrs ahead of GMT) in 1981. However many find this to be awkward as most of Malaysians (roughly 80%) live in West Malaysia rather than in East Malaysia. Malaysia is currently in effect running on the equivalent of the usual 'Spring Forward, Autumn Back' type of Daylight Saving Time found in North America and Europe. Such 'normal' DST is usually Standard Zone Time + 1 hour. Malaysia's mathematical Standard Zone Time is +7:00 GMT, hence the current +8:00 GMT is = 7 + 1 which is equivalent to the DST during the summer months in the temperate countries.
