in reply to RRD-Ping getting values on right interval

Depends on what you mean by "exactly". If it's ok to be a second or so off, it may be enough to just keep sleeping for 1 second and then checking the time to see if it's "exactly" when you need to do the next step. Just keep synchronized on system time. Beyond that, you'll have to get into milliseconds, which I'm sure someone else can supply code for (it's been too long and I don't remember the commands).
