Just a quick note of appreciation. I'm using your software for a student I teach who has many learning difficulties, but he is thrilled (and motivated) to be working with your software. Please continue the excellent work, and best of luck going forward.
Ed, Canada.

We are a homeschool family and we have been using your site for nearly 10 months now...we think you're great!

Keep up the fantastic work you do!
Warmest Regards

I have been using your programs for years now and am really glad for a chance to say how FAB they are. They are better than any other I've found for educational purposes and a fraction of the price. All the kids who have used them at my school LOVE them and I think you are a very very clever man!!

World Time Zones - software download
Size and colours reduced for screen shot

Suitable for UK Key Stage 2, 3, 4 & 5 - USA 2nd to 12th Grade (Age 7 - adult)

Recommended Minimum System: PC, Windows '95/98 or above e.g. XP, Vista, Windows 7, (Mac users click here), 16MB Ram, Pentium 90.

Please note that because of the size of the World map this program is only recommended for screen resolutions of 800x600 and above.

This fairly simple utility lets you choose your time zone when you first run it. The program will then show you the approximate times all around the world from then on. Very useful for Internet users who want some idea of what time it is for friends around the globe. Also useful as an educational tool for children. There is a further information page on World Time included with the program. Compressed file size - 725 KB.

How To Use

The main screen is a basic map of the World showing the time zones in different colours. Each hourly time zone shows a digital 12 hour clock giving the time for that zone. To change the clocks to 24 Hour mode, select Options in the top menu and click on 24 Hour Clocks. To change back to 12 Hour mode, click on this selection again to turn of the 24 Hour feature. Initially these clocks are set to your computers clock which it takes as being Greenwich Mean Time i.e. zero. The first time you run the program you have to set the map up to show your own local time and then each time zone should be shown correctly at so many hours ahead or behind this. Setting the map's clock up is achieved by clicking Setup in the top menu under Options and following the simple instructions below. This setup is saved and only needed on the initial running of the program, though it can be changed at anytime afterwards by running the setup procedure again.

The Further Information selection in Options in the top menu loads a page with more technical information about Time Zones and more general information about days, months, leap years etc.

Choosing the Setup option from the top menu produces a button for each hourly time zone next to its respective clock i.e. +1, +2, +3 hours etc. Click the hour button in or next to your nearest time zone where you live and that clock will be set to your computer's current time. All the other time clocks should automatically be reset to the correct number of hours before or after depending on where you are in the World. For instance if I were in the UK (which I am) I would click the 0 (zero) button for GMT (Greenwich Mean Time). If I lived on the West Coast of the USA or Canada (I wish) I would click the -8 button being 8 hours behind GMT. The time setting you select is saved but if you wish to alter it, just click the setup button again at anytime in the future.

Please note that this is a basic time zone map only to show for education purposes how time differences are interpreted around the World. It is not intended as a perfect chronological tool for business or navigation as for instance not all time zones exactly differ by one hour. A few are up to an extra 30 minutes ahead. This is illustrated as far as possible on my map by the hatching on those zones, though because of the scale of the map it is not possible to show every variation. The time zone boundaries are also approximate. My apologies for any areas left out or incorrect. I have tried to research the time zones as thoroughly as possible but there appear to be conflicting maps which made it even more difficult to be precise and political boundaries are often changing.

There is also the problem that some areas have daylight saving changes and these are reflected as far as possible. Nearly all (well I'm pretty sure it's all but there may be the odd tiny state which I've missed) Countries above the blue line on the map, observe Daylight Saving Time as of 29th August 1999 when I made this program. This means that on or around the 21st March each year, the clocks go forward one hour and on or around the 21st October they go back again. This means that the days remain lighter in the evenings. These dates do vary slightly as the authorities try to make the change happen on the nearest Sunday morning at about 2.00 a.m. This is to allow for those who work weekdays who might forget to put their clocks forward or back and end up being late/early for work the next day. Countries South of the line will notice that the time above the line for their time zone is an hour ahead during these times of the year. Some Southern Hemisphere Countries also have DST (Daylight Saving Times) which vary between dates in September, October and November until February and March, depending on which Country. Check out The World Clock. Apologies for Daylight Saving Areas left out. Place your mouse pointer over the time zone clocks to give more information about each.

An extra feature in this new version of the program is a small control panel in the top centre of the screen. The three buttons on this panel under the GMT clock, allow you to move all the clocks forward or back in hourly steps. So for instance, if you wanted to know what time it would be in another country at a certain time in your own, just advance the clocks to that time. Every hour the whole display is updated, so if you use this feature near to the hour, then your clocks will be set back to the correct time when the hour changes i.e. if you close the program and you have advanced all the clocks, this is not saved and the correct times will be shown when the program is started again. Click the middle green triangle button to reset the clocks back to the current time.

Thanks for the TERRIFIC software at a great price!

I've been a happy Olltwit user for years - I downloaded several of your programs back in '04, for my older son to use. Now it's time for my younger son to use them, and I've come back to your site to find 1) I owe you, and 2) you have more great stuff. I'm happy to pay up because I know the quality of your programs.
