Subject:      rolling 30 minutes descriptive statistics

Dear folks,

I have a set of time-series intra-day data and I would wish to investigate
the descriptive statistics from every 30 mins. What I have done is to set
the conditions between times using 'select when' to compute it. Just
wondering if there are any more efficient way of computing a rolling 30
mins descriptive statistics.Please advise.

Help and comments greatly appreciated.
