+	 * public birthday greetings when they haven't made this info public. 
+	 *
+	 * Assuming we are able to publish this info, we are then going to convert
+	 * the start time from the owner's timezone to UTC. 
+	 *
+	 * This will potentially solve the problem found with some social networks
+	 * where birthdays are converted to the viewer's timezone and salutations from
+	 * elsewhere in the world show up on the wrong day. We will convert it to the
+	 * viewer's timezone also, but first we are going to convert it from the birthday
+	 * person's timezone to GMT - so the viewer may find the birthday starting at
+	 * 6:00PM the day before, but that will correspond to midnight to the birthday person.
