World Time Explorer

World Time Explorer is a free and useful PC program which can show you the local time in any of the countries in the world. To see the local time for a country is as simple as clicking on it from a list of time zones represented by country and city.

There are around 409 time zones and 4815 cities to choose from. The cities in the world are evenly chosen so that most cities with more than 100,000 inhabitants are included. US cities with more than 40,000 inhabitants are included.

When running first time you have to tell which country and city you are in. Then the GMT time and the local time of seven other countries can be displayed. You can also view past and future times, which makes it easy to make appointments with friends and family in other countries at a future date.

You can get the daylight saving start and end dates for any of the 4815 cities in the world included in the program (if applicable). Common zone abbreviations like Eastern Standard Time (EST) are also displayed.

The program checks automatically each 5 times it is run if there has been changes to the time zone information. You will also be notified if there is a new version of the program.

When downloading new time zone information from the program, you will get a description of which time zone changes have been made, and you can later revise this file which is saved on your hard disk. In practical terms you don't have to worry about when the time zone information changes in the world, just click OK when it offers you to download an update.

There is a search function for a given text in countries or cities. You can also use it to more specific searches, finding capitals, time zones with daylight saving etc. You can choose between seeing all 4815 cities or just the distinct 409 cities and switch dynamically between those two settings.
