To round a timestamp to ten minutes ...

Get the timestamp as a string using datetime(now)
    --> "YYYY-MM-DD HH:MM:SS"

Get the first 15 characters of it using substr(X,1,15)
    --> "YYYY-MM-DD HH:M"

Append "0:00" using the || operator
    --> "YYYY-MM-DD HH:M0:00"

All together now:

    substr(datetime(now),1,15) || "0:00"

Then convert the string back into whatever form you want to store your dates in.

If you do this to two times close together, you may end up with two results 
which are the same.  In other words, your timestamp field cannot have a UNIQUE
