Nowhere in your posted code is a variable with name $date_time shown, yet Perl reports a variable with that name as causing the warning. Either Perl made up the variable name on the spot or you didn't show us the code that's causing this (D:/upload/Websites/iic2/lib/iic2/Controller/tests/report.pm).

Arghh, sorry Corian, I forgot I'd slightly changed the output since the first post. Restoring the code and re-running the trace gives the same output with the exception that the $date_time warning changes to...

Thanks, Rob

If the value in the date_time column is not null, then the value in the time_taken column is null, which gets turned into undef I guess.
