I'm not sure what you mean by wanting the running average at just a number of time stamps. Is this similar to what you want to do?

IDL> a=randomn(seed,1000)
IDL> cgplot,a
IDL> N=10
IDL> b=convol(a,replicate(1.,N)/N)
IDL> cgplot,/over,b,color='red'
IDL> N=100
IDL> b=convol(a,replicate(1.,N)/N)
IDL> cgplot,/over,b,color='blue'

Then you just have to figure out N for the time scales you are interested in.
