The test labeled "time()" was the faster by 0.0707 seconds, (5.888% faster)

time() 100%

microtime(true) 94.112%

The time() test took 1.1306 seconds.
The microtime(true) test took 1.2014 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 289,611 loops for a total of 5,792,220 runs.

Line execution difference (0.000012) milliseconds.
Avg difference (3.537) milliseconds per 289,611 loops.
Total difference 70.73 milliseconds for 5,792,220 loops

The iteration variablity for Code 1 was (6.0614) milliseconds and Code 2 was (6.0785) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "time()", was:

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = time();

The second test, "microtime(true)", was:

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = microtime(true);
