| 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. |
