* Determine the next birthday, but only if the birthday is published
* in the default profile. We _could_ also look for a private profile that the
* recipient can see, but somebody could get mad at us if they start getting
* 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.
