Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 266,093 loops for a total of 5,321,860 runs.

Line execution difference (0.000008) milliseconds.
Avg difference (2.194) milliseconds per 266,093 loops.
Total difference 43.89 milliseconds for 5,321,860 loops

The iteration variablity for Code 1 was (5.0521) milliseconds and Code 2 was (3.5291) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = date('Y-m-d \\a\\t H:i:s', $GLOBALS['t']);

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

for ($i = 0; $i < 100; $i++)
	$GLOBALS['dummy'] = strftime('%Y-%m-%d at %H:%M:%S', $GLOBALS['t']);
