The date fields are created with the 'timestamptz' type under PostgreSQL so the
time zone should be supported.
in this case, 'wfTimestamp' (GlobalFunctions.php) can receive a date like this
one : '2006-07-11 10:36:00+02'.

I propose to add these lines : 
function wfTimestamp($outputtype=TS_UNIX,$ts=0) {
	$uts = 0;
	$da = array();
	if ($ts==0) {
		$uts=time();
	} elseif (preg_match("/^(\d{4})\-(\d\d)\-(\d\d)
(\d\d):(\d\d):(\d\d)$/D",$ts,$da)) {
		# TS_DB
		$uts=gmmktime((int)$da[4],(int)$da[5],(int)$da[6],
			    (int)$da[2],(int)$da[3],(int)$da[1]);
+	} elseif (preg_match("/^(\d{4})\-(\d\d)\-(\d\d)
(\d\d):(\d\d):(\d\d)\+(\d\d)$/D",$ts,$da)) {
+		# TS_DBTZ
+		$uts=gmmktime((int)$da[4] + (int)$da[7],(int)$da[5],(int)$da[6],
+			    (int)$da[2],(int)$da[3],(int)$da[1]);
