| /* |
| * This test was contributed in a different form by W. McDonald Buck |
| * of Boulder, Colorado, to help fix some bugs with the FTPClientConfig |
| * in a real world setting. It is a perfect functional test for the |
| * Time Zone functionality of FTPClientConfig. |
| * |
| * A publicly accessible FTP server at the US National Oceanographic and |
| * Atmospheric Adminstration houses a directory which contains |
| * 300 files, named sn.0000 to sn.0300. Every ten minutes or so |
| * the next file in sequence is rewritten with new data. Thus the directory |
| * contains observations for more than 24 hours of data. Since the server |
| * has its clock set to GMT this is an excellent functional test for any |
| * machine in a different time zone. |
| * |
| * Noteworthy is the fact that the ftp routines in some web browsers don't |
| * work as well as this. They can't, since they have no way of knowing the |
| * server's time zone. Depending on the local machine's position relative |
| * to GMT and the time of day, the browsers may decide that a timestamp |
| * would be in the future if given the current year, so they assume the |
| * year to be last year. This illustrates the value of FTPClientConfig's |
| * time zone functionality. |
