Never mind the granularity or latency, there are systems where "time of day" can be adjusted to take into account clock drift, while "system elapsed time" is left unaffected. Which you want depends on whether you want to sleep for a specific time, or wake up at a specific time, and it would be nice if Parrot didn't rule out making use of that. -Martin
