Alright, imagine you have a big clock that shows the time, just like the one you might have in your room. But there are many clocks all around the world, and they all show slightly different times because some places are ahead of others and some are behind.
Now, grown-ups wanted to make things simpler, so they decided to have one special clock that shows the time for the entire world. This special clock is called UTC, which stands for “Coordinated Universal Time.” It’s like a superhero clock that everyone agrees to follow, so we all have the same time everywhere.
No matter where you are, when it’s the same time on your clock as on the UTC clock, it means everyone else in the world also sees the same time on their clocks. This helps people from different places work together and understand each other’s schedules easily!
So, UTC is like the boss of all the clocks around the world, making sure we’re all on the same page and know exactly what time it is.
Alright, imagine you have a friend who lives in a different country, far away from you. They have a special clock called GMT, which stands for “Greenwich Mean Time.”
Now, where they live, there’s a special place called Greenwich, and that’s where the GMT clock was created. It’s like the headquarters of all the time zones.
When your friend tells you the time using GMT, they are using the time in Greenwich as a reference. So, when they say it’s 12 o’clock GMT, it means it’s like the “main time” for the whole world.
But here’s the fun part! Not all places in the world have the same time. Some places are ahead of Greenwich, and some are behind. It’s because the Earth is so big that when it’s daytime in one place, it’s nighttime in another.
So, your friend’s GMT clock helps them talk to other people in different time zones. They can say, “I’ll call you at 3 o’clock GMT,” and you’ll know what time it is for you, even if you live in a different part of the world.
GMT is like a time-sharing superhero that helps people from different countries understand what time they mean, so they can talk and do things together, even though they’re far away!
