The MOM 2005 SDK incorrectly documents the ScriptContext.Sleep method for temporarily pausing a script as seconds :
[VBScript] ScriptContext.Sleep(seconds As Long)
This is documented incorrectly. It should be
[VBScript] ScriptContext.Sleep(milliseconds As Long)
ScriptContext.Sleep (60000) 'This will pause for 1 minute.
The error in question is on http://msdn.microsoft.com/library/default.asp?url=/library/en-us/momsdk/HTM/R_Script/MOM_IEEMScriptContext.Sleep.asp
There are no plans to change the above link as it would then conflict with the content downloadable in the SDK (momsdk.chm), which also documents this incorrectly.
A KB article documenting this issue will be forthcoming shortly.
