## 14.2 Capturing the Start Time

The `capture` procedure of PLVtmr allows you to capture the start time for a timing session. Its header is:

>     PROCEDURE capture (context_in IN VARCHAR2 := NULL);

The single argument supplies a context which is associated with this timing session. When you call `capture`, PLVtmr in turn calls DBMS_UTILITY.GET_TIME to "capture the moment."

The following call to `capture` starts the timing session and assigns it the name "Calculating Totals":

>     PLVtmr.capture ('Calculating Totals');
