I have been combing through multiple forums and excel formula code but cannot find anything to help me out.

I have thousands of strings I need to parse through to extract out a specific date. The date location has no specific parameters around it to easily extract it out. The location from the beginning or the end varies with every string. The only thing that is consistent is a message that reads "Changed Status to Subtasks Created" which can be displayed anywhere from 20 characters to 660 characters after the date we need to extract.

Here is a snippet:
Changed Item Details to CTS Details:
02/15/2013 9:49 AM Escalated Changed Details_1 to CTS Details:
02/15/2013 9:49 AM Escalated Changed Details_2 to
Changed Details_3 to
Added the following Subtasks to this Request: 146448.
Escalated: Rename Master Ticket - NH
Deleted Assignee: UAM
Changed Status to Subtasks Created from Generating Subtasks
Changed Request Title
Changed Initial Approval to None
Changed Additional Approval to No
Changed Ticket Item to
02/15/2013 12:14 PM Escalated Changed Status to Closed from Subtasks Created

So I need to extract then 02/15/2013 9:49 AM text out of this string. The above snippet has 4200 characters in front of what I showed above. Can anyone help?
