hi there - this is something I have been struggling with for ages. Is it possible to be able to select a range of dates, and a time interval, and then to automatically fill in cells in a column? to be more specific, I want to be able to select, say 1 Jan 2013 to 31 dec 2013 in one box, then specify a time interval, for example "hourly" and then a column is populated with each interval, i.e. 1 jan 2013 00:00, and then the next one is 1 jan 2013 01:00 etc. I have tired the normal automatic fill tool but it never seems to get it right. It works for the first few days then it all goes funny.

thanks in advance for the help
Gary
