Almonds bloom rather early, about end of February to beginning of March(http://209.85.135.104/search?q=cache:QQDAQzdaYY0J:ressources.ciheam.org/om/pdf/c56/01600204.pdf+Flowering+time%2Balmond&hl=de&ct=clnk &cd=6&gl=de) and apricots flowering time is end of March to middle of April (http://www.azaran.org.ir/symposiumcd/papers/Dejampour.htm), so cross pollinating shouldn`t take place.

There is a cultivated variety of apricot, called almond-apricot (Armeniaca amygdalina Dochnahl), a fruit with a soft, edible, almondlike pit, but that isn`t a hybrid of almond and apricot.
