Daylight Savings Time

Daylight Savings Time (DST) has been implemented within Australia in various forms since the early 1900s. Since it began, the times at which weather observations were made by the Bureau of Meteorology during the period of DST also underwent a number of changes in practice. In different years an observation may have been made based either on local clock time, or according to local standard time ignoring DST. The impact of these changes is probably most significant on the nominal 9am data, particularly temperature and humidity observations.
