What is the code you're using to construct the WTM? If it's something like:

WorldTimeMorph new openInWorld

then you can just go:

wtm _ WorldTimeMorph new openInWorld.
"and later"
wtm delete.

Or to delete all WorldTimeMorphs from the current world:

World allMorphsDo: [ :ea | (ea isKindOf: WorldTimeMorph) ifTrue: [ ea delete 
]]
