The strftime() test took 1.2141 seconds.
The localtime() test took 1.3104 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 279,201 loops for a total of 5,584,020 runs.

Line execution difference (0.000017) milliseconds.
Avg difference (4.817) milliseconds per 279,201 loops.
Total difference 96.34 milliseconds for 5,584,020 loops

The iteration variablity for Code 1 was (6.2225) milliseconds and Code 2 was (11.3835) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = (int) strftime('%d', $GLOBALS['t']);

The second test, "localtime()", was:

for ($i = 0; $i < 100; $i++)
{
	$temp = localtime($GLOBALS['t'], true);
	$GLOBALS['dummy'] = $temp['tm_mday'];
}
