Splunk and dd/mm/yyyy dates

Anyone here use SPLUNK for data logging.  It does a very good job of logging data from multiple event logs and flat log files (IIS Logs), but I've hit a problem with format of the credit card log file.  It returns the data as 

dd/mm/yyyy

but the program is expecting 

mm/dd/yyyy or yyyy/mm/dd

I've spent most of today attempting to override this with XML and .conf files, but have failed.  If anyone has any info or suggestions they can contribute, I'd be grateful.

 

I've also posted to the Splunk forums so you can see the full story
