I don't think this is a cause for concern.  Polling will often take
varying times as it depends on server and network loading.  However,
MRTG compensates for this by adjusting its internal rates based on the
data logging times, so if the poll happens a few seconds late, then the
rate of change will be very slightly adjusted to reflect this.  If you
use gauge, though, I think the numbers may be logged as-is to the data
time window.
