           Summary: cl.snap.servertime < cl.oldframeservertime error
           Product: ioquake3
           Version: 1.36
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Platform

When issuing a "nextmap" or "map", the clients gets randomly kicked out with
the error message "cl.snap.servertime < cl.oldframeservertime".

Tests and conclusions :

This bug only happens with "nextmap" or "map", never with "map_restart".

It happens with unedited versions of GTV3.

Trying to connect a quake 3 client to a GTV3 server connected to a quake 3
server works flawlessly.
Trying to connect a quake 3 client to a GTV3 server connected to an ioquake3
server produce the error. (I tried with old revisions, about as old as it was
possible to compile with mingw, like v560).

Now the last significant test : I tried to set cl_TimeDelta 1 inside the GTV
server and the q3 client.
The results were pretty astounding : while quake 3 server increases a lot the
TimeDelta at "map", an ioquake3 server instead decreases it a lot ! What is
interesting is that the difference in behaviour only happens when issuing a
"map", when doing a "map_restart", both servers increases a little their
values.

Tested on Windows (Windows XP, Vista and Seven) and Linux (Gentoo and Debian).
