These timestamp literals represent exactly the same moment, and therefore have exactly the same internal representation: timestamp '2008-01-31 12:31:40.50' timestamp '2008-01-31 12:31:40.500' timestamp '2008-01-31 12:31:40.500000' to_char turns that into a string of your chosen format. I hope that helps. -Kevin
