Bug description: xmlrpc_decode ignores time zone on iso8601.datetime
Description:
------------
The xmlrpc_decode function does not correctly interpret ISO 8601 timezone
designations when interpreting XML-RPC datetime values passed in
<dateTime.iso8601> tags. It appears that the time zone designator is
completely ignored and the local time zone is assumed. (The
xmlrpc_decode_request function shows the same behavior.)
A side effect of this bug is that the 'scalar' and 'timestamp' objects
returned for XML-RPC datetime values will disagree if the object is used is
used in a different time zone than it was created. Ideally the scalar
property should explicitly be a UTC ISO 8601 datetime value, ending with
the time zone designator 'Z'.
Reproduce code:
---------------
function DecodeDatetime($datetime) {
print "\nISO 8601 datetime $datetime\n";
print "strtotime yields " . strtotime($datetime) . "\nxmlrpc_decode
yields ";
$obj = xmlrpc_decode("<?xml
version=\"1.0\"?><methodResponse><params><param><value><dateTime.iso8601>$datetime</dateTime.iso8601></value></param></params></methodResponse>");
print_r($obj);
}
DecodeDatetime("20010909T01:46:40Z");
DecodeDatetime("20010909T00:46:40-01");
DecodeDatetime("2001-09-09T08:46:40+07:00");
DecodeDatetime("2001-09-08T21:46:40-0400");
Expected result:
----------------
The ISO 8601 datetime strings tested above are all valid and equivalent
They all represent the same timestamp as the unix time 1000000000, and
strtotime() function converts them all correctly. I would expect that the
object returned by xml_rpc decode should, in all four test cases, have the
timestamp property = 1000000000 and have the scalar property as a string
that would convert to 1000000000 if fed to strtotime().
Actual result:
--------------
The xmlrpc_decode function gets them all wrong except for the last one,
which happens to have the same time zone as my test system:
ISO 8601 datetime 20010909T01:46:40Z
strtotime yields 1000000000
xmlrpc_decode yields stdClass Object
(
[scalar] => 20010909T01:46:40
[xmlrpc_type] => datetime
[timestamp] => 1000014400
)
ISO 8601 datetime 20010909T00:46:40-01
strtotime yields 1000000000
xmlrpc_decode yields stdClass Object
(
[scalar] => 20010909T00:46:40
[xmlrpc_type] => datetime
[timestamp] => 1000010800
)
ISO 8601 datetime 2001-09-09T08:46:40+07:00
strtotime yields 1000000000
xmlrpc_decode yields stdClass Object
(
[scalar] => 20010909T08:46:40
[xmlrpc_type] => datetime
[timestamp] => 1000039600
)
ISO 8601 datetime 2001-09-08T21:46:40-0400
strtotime yields 1000000000
xmlrpc_decode yields stdClass Object
(
[scalar] => 20010908T21:46:40
[xmlrpc_type] => datetime
[timestamp] => 1000000000
)
