    In mid-2003, someone in the Lounge asked for a list of time zones. I said that I had one, but the data was in a CodeBase/FoxBase file. Chris Maunder asked if I could retrieve that data and submit it to CodeProject. After procrastinating a few weeks, I decided to go ahead and not only extract the data, but to write a program to edit that data.
