Subject: timezeone adjustment Date: 2017-06-09 11:22:13 From: nicolas nicolas Source: timezeone-adjustment ----------------------------------------------------------------------hi,
I made a test about file uploading and timezone adjustments
[code lang='c#']
public static void proc_test()
{
Ftp ftp;
ComponentPro.IO.FileInfoCollection files1;
ftp = new Ftp();
ftp.Connect ("theftpcomputer",21);
ftp.Authenticate("myuser", "mypassword");
Console.WriteLine ("ServerTimeZoneOffset=" + ftp.ServerTimeZoneOffset );
Console.WriteLine (" RestoreFileProperties=" + ftp. RestoreFileProperties);
ftp.Upload (@"D:\temp\dir1\x3.txt", @"/dir1/xx3");
ftp.SetCurrentDirectory (@"/dir1/xx3");
files1 = ftp.ListDirectory();
foreach (FtpFileInfo f in files1)
{
if (f.FullName.ToLower().Contains ("x3.txt") == true)
Console.WriteLine ("File=" + f.FullName + " CreationTime=" + f.CreationTime + " LastWriteTime=" + f.LastWriteTime + " Size=" + f.Length);
}
}
[/code]
the result was run at 14:10 and is the following:
ServerTimeZoneOffset=00:00:00
RestoreFileProperties=False
File=/dir1/xx3/x3.txt CreationTime=01/01/0001 00:00:00 LastWriteTime=09/06/2017 16:10:27 Size=12
on the ftp server (windows) , when I check the file :
C:\ftp\n\dir1\xx3>dir x3.txt
Le volume dans le lecteur C s'appelle disk_system
Le numéro de série du volume est 7471-F7A5
Répertoire de C:\ftp\n\dir1\xx3
09/06/2017 14:10 <REP> .
09/06/2017 14:10 <REP> ..
09/06/2017 14:10 12 x3.txt
1 fichier(s) 12 octets
the source computer and the ftp server are located in the same area, in the same TZ : UTC+1
why do the listedirectory() command from ftp class made "internally" an adjustement of 2 HOURS while the offset is zero
UPDATE:
------------------
I made a new test adding the log file option. running at 14:53 (UTC+1),
again, the list directory() report a delta of 2 hours for the file but the log file report that the ftp server send the correct timestamp
