you wan to tell SQL the value contained in the perl "$tim" variable, so you require perl's interpolation for THAT variable, so , use double-quotes.

Wrong. Most SQL engines require single quotes for values, and double quotes for otherwise illegal identifiers.

But don't use single-quotes, either. Use placeholders and only placeholders for any value passed to the database. Forget that quote exists at all. That method should be restricted to DBDs.

Use quote_identifier when you need to pass variable identifiers (most times, names of database objects like tables, views, columns, triggers, sequences, procedures) to the database.

Update: Sorry, I wrote nonsense.
