Description:
------------
The test script, ext/standard/tests/time/002.phpt always fails on AIX because AIX does not support setting of TZ to US/Eastern, and the if statement that checks for this situation fails.

Orignal code in test case:

        putenv("TZ=US/Eastern");

        if( date("T") == "GMT" ) {
                // POSIX style
                putenv ("TZ=EST5EDT4,M4.1.0,M10.5.0");
        }

should be modified as follows:

        putenv("TZ=US/Eastern");

        if( date("T") == "GMT" || date("T") == "   " ) {
                // POSIX style
                putenv ("TZ=EST5EDT4,M4.1.0,M10.5.0");
        }

Then it will pass the test. IMHO this problem applies to several platforms, not just AIX. The function date("t") could return a string of three spaces under certain circumstances.

Reproduce code:
---------------
base=`pwd`
cd ext/standard/tests/time
export TEST_PHP_EXECUTABLE=$base/sapi/cli/php
$TEST_PHP_EXECUTABLE $base/run-tests.php 002.phpt
