Excel Workbook Error: java.lang.IllegalArgumentException: Illegal pattern character 'T'

When attempting to convert an excel workbook to PDF using cells-java, this error is being thrown:
java.lang.IllegalArgumentException: Illegal pattern character ‘T’ I’m assuiming the error is related to a Date/Time conversion issue. Is this a known issue? Any workaround suggested?
