Maybe, it would be better to use given name + patonymic instead of «д-р Мовсесов».

I don't think that the phrase «Доброго времени суток» is a humorous internet-newspeak greeting. It's a more relaxing way to put greeting. We don't use it in official conversation, but in that case it is normal. I would have used it in that variant. Moreover, Aerospallo girlfriend's father will understand that his future son-in isn't а snob and a nudnik, but a great conversationalist.
P.S. I agree "Добрый день" is OK too)))
