On 32bit systems a long can hold numbers up to\napproximately two billion.  The number of TICKS_PER_HOUR is really large,\n(32768 * 3600) or roughly a hundred million.  When you start multiplying\nby a hundred million it doesn't take long to overflow the two billion\nmark.\n\nProbably the safest way to fix this is to change the type of\nTICKS_PER_HOUR to long long because it's such a large number."
