Extract data based on time

[MAY]

I have a data logger that collects data every 5 seconds from 2 sources. I
have imported the data into 2 tables. How can I extract data every 5 minutes
at the hh:mm:00 time value (i.e. at 0 seconds) – so that I can perform
calculations on the extracted data at the same time values

In a report you could use the sorting and grouping options to group on a
date/time field and set it to 5.
