Gchart is a Google Map powered application which can help you find out the current time around the world. I usually use Time and Date, but Gchart is pretty useful when I need to find the current time on the area quickly. All I need is to load up the site, click on the area I need to find and it will display the current date, time, city, state, country, telephone country code and area code.
Added to Essential Resources for Google Maps‘s Top 10 list.
Take a look at one mashup I worked on: http://www.mapservices.org/myguestmap
It’s free ;)
