Sounds reasonable. On the other hand, plural indirectly underlines the usual need of multiple timer 
task instances. I let it up to you.     in other respects the wording looks okay to me.

I still like to see the extended explanation for the IllegalStateExeption at Timer.schedule(...), 
even if technically redundant, as one might miss the note at TimerTask.
