Upon Namibian independencethe country used a single time zone, keeping time regulation as previously prescribed by the occupying nation, South Africa. Triggered by fears for school children walking to school before sunrise, discussions in the National Assembly started in 1992, and on 10 November 1993 the Namibian Time Bill was proposed. This bill defined the Namibian Standard Time.
1994–2017
From 1994 until 2017 Namibia used Winter time, the practice of setting clocks back during winter months by one hour. In this period Namibian Standard Time was at Central Africa Time in summer, and in winter. Winter time began on the first Sunday in April at 03:00, and lasted until the first Sunday in September, 02:00 hours. In the Zambezi Region in the far north-east of Namibia clocks were not changed and remained on Central Africa Time all year round so that during winter time, Namibia spanned two time zones. The Namibian Standard Time was thus in summer, and in winter. Namibia was one of only a few countries in the world to implement winter time instead of daylight saving time. Ireland still adjusts clocks in Winter since 1971 while Czechoslovakia used the practice only in 1946 and never repeated it. In a regular daylight saving time scheme, the "normal" time is observed in the winter, and clocks are turned forward during the summer. In winter time, normal time is observed in the summer, and clocks are turned back by one hour in the winter. In timekeeping, then, it is equivalent to daylight saving time, differing only in which season is considered the regular time. However, the purpose was not to utilise additional hours of daylight in the evening, but to prevent children from walking to school in darkness in the morning, to decrease the risk of injuries and assaults. If expressed as summer times, these would have been equivalent to West Africa Summer Time and West Africa Standard Time, however Namibia was the only state in Africa to use the combination of and. Central European Time also uses and, but the northern seasons are opposite to the southern hemisphere.
Since 2017
In the 2010s repeated calls from businesses and private individuals were made to abolish winter time, citing incompatibilities with South Africa, Namibia's main trading partner, as well as a "loss of productivity". This resulted in an official investigation by the Ministry of Home Affairs and Immigration. During the polls, 97% of the 3,507 questioned people were in favour of the +2 difference to Greenwich Mean Time, and about 88% wanted to abolish winter time. After the Cabinet was likewise against changing clocks in autumn and spring, minister Pendukeni Iivula-Ithana proposed a new bill to that effect in February 2017. The Home Affairs ministry stated that winter time would proceed in 2017, as discussions were still ongoing. The National Council passed the Namibian Time Bill 2017 in August 2017 and repealed the 1993 act.
