Delay a Timer Event for Exact 1 Second

I want to delay the Timer Event for Exactly for 1 second and followed the appian recommneded process  accordingly still there has been no effect 

The Duration of that node is always less than 1 second some times  like 0.58,0.060.8,0.36 these were the values seen.
I want to see Exactly 1 second.

Is there a way to configure to delay the node for exactly one second

Thanks In Advance
