Daylight Savings Time

Daylight savings here in Melbourne starts tomorrow morning 29 Oct 06 at 2am and ends 2am Sunday, 25 March 07.
My family and friends in Singapore always ask me why I am 3 hours ahead of them . This is what I found on the internet to help explain DST...

What is daylight savings ?

Daylight Saving Time (or Summer Time as it is called in many countries) is a way of getting more out of the summer days by advancing the clocks by one hour during the summer. Then, the sun will appear to rise one hour later in the morning when people are usually asleep anyway, at the benefit of one hour longer evenings when awake: The sunset and sunrise are one hour later than during normal time. DST could save energy (less artificial light is needed during the evening) and make the country more efficient in addition to the pleasing effect of lighter evenings. To make DST work, the clocks have to be adjusted one hour ahead when DST begins (during spring), and adjusted back one hour to standard time every autumn. There are many countries observing DST, and many who do not.
Daylight Saving Time is difficult to predict in future, many countries change the transition days/principles every year because of special happenings or conditions that has happened or will happen.
