Time Zone Helper

Time Zone Helper is a utility that allows you to see an E-mail's time zone and current time with one click, and generate a time zone chart with one more click. Time Zone Helper lets you set up different time zones for the people you talk to across the world.

You can paste a time zone overlap chart into the E-mail you send, so you can help to organize a meeting at the right time. The chart can be customized with names, locations and time zones, and even shows which people are on the same day of the week.
