From the developer: "ecAreaCodes is a desktop tool that retrieves telephone area code information. It also retrieves phone numbers stored in Microsoft Outlook items. If you use the telephone in your job then you need this program. It allows you to quickly find the time zone and location for each area code in the US and Canada. With that, you can determine if "Now" is a good time to call someone. It helps you answer questions like: Are they there yet? Are they likely at lunch? and Have they gone home? Importantly, ecAreaCodes does not use the Internet, so you can work off-line. Finally, It does not contain advertising or require you to give out your personal information."
