See Timers in the documentation for details and examples.

Syntax

The name of the timer to log to the console.

Return

If no label parameter included:

If an existing label is included:

Exceptions

If there is no running timer, timeLog() returns the warning:

Timer “default” doesn’t exist.

If a label parameter is include but there is not corresponding timer:

 Timer “timer name” doesn’t exist. 

Examples

console.time("answer time");
alert("Click to continue");
console.timeLog("answer time");
alert("Do a bunch of other stuff...");

The output from the example above shows the time taken by the user to dismiss the first alert box, followed by the time it took for the user to dismiss the second alert:
