History ColdFusion MX 7: Added this tag.
Usage 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 MX Administrator.
