My math program offered a (difficult) upper division History of Math course at least. But to your point, I'd categorize undergraduate mathematics as being atemporal rather than ahistorical. On the other hand, computer science programs (at least of the so-called "Java School" variety) seem to have an antipathy for the past rather than a mere disinterest.
