Do you only want the HH:MM:SS of the data? What are you going to do with it? You can 'extract' it with
format(hora, "%H%:%M:%S") If you don't want the date and are only working with the hours in a single day, then convert the time to a numeric value of hours (or minutes), whichever is appropriate. So an idea of what you are actually after and how you plan to use it will help guide some advice. On Fri, Mar 20, 2009 at 12:59 PM, Paulo E.
