You have a table named AuditTrail that tracks modifications to data in other tables. The AuditTrail table is
updated by many processes. Data input into AuditTrail may contain improperly formatted date time values. You
implement a process that retrieves data from the various columns in AuditTrail, but sometimes the process
throws an error when it is unable to convert the data into valid date time values.
You need to convert the data into a valid date time value using the en-US format culture code. If the conversion
fails, a null value must be returned in the column output. The conversion process must not throw an error.
