Hi!

How would one go about to construct a query that counts items within an increment or span of time, let's say increments of 10 minutes? Imagine a simple table where each row has a timestamp, and the query should return the count of items occurring within the timespan of a defined period.

Say,

09:00: 14
09:10: 31
09:20: 25
09:30:  0
09:40: 12

etc.

I have been able to get collections of item occurrence based on month and day by using GROUP BY together with a DATE_FORMAT( start_time, "%d %m %Y" ) eg. I can however not seem to be able to find the solution to grouping based on the minute increments in my example above.

Any suggestions?
