Data sorting based on time and date

Hi,

I have a spreadsheet with two columns of data that are sorted by time and date. I want to compare this data to another set of the same kind and same date range, but with different time intervals.

How can I organize the data side by side with their respective time stamps?

Cheers

Organize the columns so that the dates then times are the last of each sets of data. Highlight the most upper right cell of the data then drag to the most bottom left. Use the sort button for accending or decending order. Repeat with the other set of data and that should have done it. Let me know if you've any questions.
