Whenever you use send...in, the result is set to the message id. Sometimes people put that into a global. You could also use a property. The following allows cancelling the message with only the use of a local -- note that the local declaration outside any handlers makes it local through all the handlers, a neat trick:

local tUpdateTimeMessage

on updateTime
  put the long time into me
  send updateTime to me in 1 second
  put the result into tUpdateTimeMessage
end updateTime

on cancelUpdateTime
  cancel tUpdateTimeMessage
end cancelUpdateTime
