Well tried looking up this command in the 2.x docs, but
'docs/extcommands.html' only shows some of the external commands and
I can't find other documantation about it anywhere else.
But anyway, the command itself seems to be right because:

echo "[`date +%s`] SCHEDULE_SVC_DOWNTIME;
 linux1;PING;1108637600;1108695200;1;57600;nagios;Regularly" >>
nagios.cmd

gives the following in the Event Log:
(pointing-hand-icon) [2005-02-16 10:40:18] EXTERNAL COMMAND:
SCHEDULE_SVC_DOWNTIME;linux1;PING;1108637600;1108695200;1;57600;nagios;Regularly

though if i change it to SCHEDULE_SERVICE_DOWNTIME it gives:
(I-icon) [2005-02-16 10:39:39] Warning: Unrecognized external command
->
SCHEDULE_SERVICE_DOWNTIME;linux1;PING;1108637600;1108695200;1;57600;nagios;Regularly

Ofcourse the parameters to the SCHEDULE_SVC_COMMAND could be wrong,
for which I need the documentation, which I can't find. It would help
if Nagios would parse the parameters before logging to the Event Log
(so that a warning can be given on wrong input). Now the only thing I
can do is making wild assumptions on what the input should be.
