           Summary: Changing system time changes X timestamp
           Product: xorg
           Version: 6.8.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Server/general
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: l.lunak at suse.cz


After changing system time (e.g. going 5 months back and then going back to the 
current date triggers it in my case), the X timestamp is changed as well. This 
triggers e.g. KDE bug #90795 (http://bugs.kde.org/show_bug.cgi?id=90795). The 
best description of the timestamp I've found, in the glossary of the protocol 
specification, is a bit vague, but I think changing system time should not affect X 
timestamp. The X timestamp is no real time, and is used only to ensure ordering. 
Changing it when system time changes can e.g. make recent timestamps to become 
suddenly very old timestamp, thus breaking various things.
