timing question

[Richard P. Heitz]

I have an object running in the background that will record a response
(i.e., duration = 0, time limit = infinite).  after it begins, I present
some moving dots, which loop until the background object.rt > 0.  I am
getting a large onset delay of this background object, on the order of
several hundred ms.  Will this affect the accuracy of the *response
time* collected by that object?
