Displays execution time for a specified section of CFML code. ColdFusion displays the timing information along with any output produced by the timed code.
To permit this tag to execute, enable the Enable Debugging and the Timer Information options on the Debugging Settings page in the ColdFusion Administrator. Also, the IP address of the machine that runs ColdFusion must be added to the list of debugging IP addresses in the Debugging IP Addresses page if the request is sent by a remote machine. If the request is from a localhost, the IP address 127.0.0.1 must be present in the list of debugging IP addresses.
<cftimer label= "text" type = "inline|outline|comment|debug" > CFML statement(s) </cftimer>
You can specify this tag's attributes in an attributeCollection attribute whose value is a structure. Specify the structure name in the attributeCollection attribute and use the tag's attribute names as structure keys.

Use this tag to determine how long it takes for a block of code to execute. You can nest cftimer tags.
This tag is useful for debugging CFML code during application development. In production, you can leave cftimer tags in your code as long as you have disabled the debugging option in the ColdFusion Administrator.
