Default Averaging by half hour time intervals.

Hi all.

Working with quite a large amount of data which I have to condense from 2-3 second intervals into half hour averages. The timestamp is in column 1 with the form HH:MM:SS AM/PM (e.g 12:00:03 AM) and data of interest is in column 2.

Only problem is that as it is an odd time interval, the half hour recording is not always the same time after the end of that period (e.g. not always 12:00:00, 12:30:00, 1:00:00 etc but rather say 12:00:03, 12:30:01, 1:00:02 etc)

Any ideas?

Any help would be most appreciated.
