If the client and server time are not synchronized, orthe client and server are in different time zones, this affects incremental-by-datebackup and image backup with mode=incremental.The client backs up the files whose modification date and time (client time) is laterthan the date and time of the last incremental backup of the file system on whichthe file resides (server time).If the server time is ahead of the client time, an incremental-by-date operation orimage backup with mode=incremental skips the files, which had been created ormodified after the last incremental or image backup with a modification dateearlier than the last incremental backup time stamp.Chapter 13.
