I have a Google Spreadsheet fetching stock exchange data using an ImportHTML function:
=ImportHtml("http://www.xxxx.xx.xx/xxxxxxxx/livefeedfull.aspx/?"& year(now()) & month(now()) & day(now()) & hour(now()) & MINUTE(),"table",0)
that I then publish to a JSON which updates on every change. This function however updates every minute.
How do I set it to update at intervals of five minutes?
