PureFTPd UTIME bug
PureFTPd (as of version 1.0.21) suffers from a serious bug when setting the date/time of a file on the server using the SITE UTIME command. The file on the server gets a time which is off by several hours. As a result the keep file time feature to "synchronize" the file time of the remote file (file on the server) with the local file does not work. This has major consequences for synchronization operations which depend on the correct file time.
Comments are in blue color. Lines starting with a 3 digit number are FTP server replies. Lines without a 3 digit number are commands sent by the FTP client.
220---------- Welcome to Pure-FTPd [TLS] ----------
FTP client sends command to set time of the remote file test.txt in UTC with the SITE UTIME command:
SITE UTIME test.txt 20080825033443 20080825033443 20080825033443 UTC
FTP server acknowledges command
250 UTIME OK
FTP client sends MLST command to get the file information (time) of the remote file test.txt
FTP server returns the information. Note that the time (in red) is 5 hours off the time above (in green)
FTP client sends MDTM command to get the file time only. Note that the time (in red) is once again 5 hours off.
FTP client sends STAT command to get the "unix" like listing of the file test.txt. This listing contains the time in local time which is only of use if the server locale (timezone with daylight savings) is known.

Disable the Keep File Time option for uploads in SmartFTP. This way your files will always have the time when they have been uploaded and not the same time as the source file.
Update 22. January 2009
The bug has been fixed in the latest version of Pure-FTPd (1.0.27). Update your server software or ask your web hosting provider to do so.
