【明報專訊】Eason has hacked into Dr Panda's computer and messed up its clock! The other Smarties' watches are synchronised with it and therefore also not showing the correct time. Worse still, they are in different time zones! How does time differ around the world?

We have days and nights because the Earth rotates around its own axis, and only a part of it receives sunlight. It is daytime when the sun shines on where you live and, simultaneously it is night-time elsewhere. When you are having a class, children in London (倫敦) are in bed and those in Sydney (悉尼) may have finished school!

Day and night

The countries in the world fall into different time zone(s). The prime meridian, at which longitude is defined to be 0 degree, runs through Greenwich (格林威治), London. There are 24 standard time zones. The time difference between a time zone and an adjacent one is one hour. Hong Kong is in the Eastern hemisphere, and is in the GMT+8 time zone. That means Hong Kong is 8 hours ahead of Greenwich Mean Time (格林威治標準時)!

Time zone

“ Dr Panda: Big Ben is accurate to within one second. I can use it to reset the time! ”
