Cambodia's clock over the years

Five places in one database entry: 5places, Cambodia among them, under one time zone database entry; The time zone database files Cambodia in a single entry with four other places. They are Christmas Island, Laos, Thailand and northern Vietnam. All of them keep UTC+7 today. So a clock in Laos or on Christmas Island shows the same time as one in Phnom Penh.; Source IANA tz database, file 'asia' (Cambodia listed under Asia/Bangkok; Indochina history under Asia/Ho_Chi_Minh)
Mean time in Phnom Penh: 20 show far Phnom Penh's old mean time fell short of the present offset; Phnom Penh's history in the database opens on the city's own mean time. That fell twenty seconds short of the offset Cambodia keeps now. The file moves on from it in the first decade of the twentieth century.; Source IANA tz database, file 'backzone' (Cambodia section, Asia/Phnom_Penh)
One account of the war years: UTC+7the offset that account says Cambodia kept after independence; A note in the time zone database passes on one account of the war years and after. It says Cambodia fell under French rule again once Japan had surrendered. Cambodia then took up Hanoi's time zone once more. Later the zone stood seven hours ahead of Greenwich mean time, with no daylight saving. That offset held after full independence.; Source IANA tz database, file 'backzone' (Cambodia section, Asia/Phnom_Penh)
