IntlDateFormatter::localtime broken example

Issue description

Run the example code, you'll get an error. This makes sense because the $offset is passed as an integer but you can't because the argument is a reference.

Steps to reproduce

Run the examples.

Suggested fix

Probably introduce a variable $offset, set it to 0, and pass that.

Actually, even after doing the proposed fix the output is just empty, not the output listed in the manual. cc @devnexen

It happens that the format should be
'Wednesday, December 31, 1969 at 4:00:00 PM Pacific Standard Time'

This can be checked with
echo datefmt_format( $fmt , 0);

Also, the output should be changed to:
First parsed output is tm_sec : 0 , tm_min : 0 , tm_hour : 16 , tm_year : 69 , tm_mday : 31 , tm_wday : 3 , tm_yday : 365 , tm_mon : 11 , tm_isdst : 0 ,
