Hello,
When using rt linux, does it mean that the jitter is in both direction
or only bigger than amount of time for wait ?
For example, if we set periodic timer for 1msec, can it also be that
we get the interrupt before the 1msec period ended ?
Thank you.

With or without RT: the timer must not fire too early. I can fire
_after_ the 1ms deadline but never before that.
