This is only listing the first Date of the following example: cbum 5/9/2011 2:55:18 PM LS ->> LS‡Hi cbum 5/9/2011 2:55:17 PM LS‡Hi ->> LS Kristen UZlab Kristen 4/29/2011 4:27:28 PM CU‡Hi ->> CU‡Hi‡LS Kristen UZlab Kristen 4/29/2011 4:27:28 PM [---] ->> CU‡Hi Why?

Hi, sorry, this is a very old function, but my guess is that you're using a non-American date format DD/MM/YYYY, and this text is formatted MM/DD/YYYY.

Did a great job for me. Put the results (Replace field contents) into a date field which converted all dates found to DD/MM/YYYY. I imagine it would not be difficult to edit the function to handle US dates or ISO 8601 dates.
