Date Time field not reading api input correctly

Date Time field not reading api input correctly

I've run into a strange issue which probably has a simple solution. When I am inserting a record, I have a field that maps to a date time field. When I look at the xml before it is sent it has a value of 08/22/2015 11:59 AM. The insert processes fine  into the leads module and I get a success message back. However when I go and look at the record in leads the field reads  01/22/2015 11:59 AM. I have tried altering the date to 1 digit for the month and also changing it to other months including 2 digit months but it still reads the month as 01. 

Any ideas?

Thanks
