// Computes (value*numer)/denom without overflow, as long as both
// (numer*denom) and the overall result fit into i64 (which is the case
// for our time conversions).

  int64_t q = value / denom;
  int64_t r = value % denom;
  // Decompose value as (value/denom*denom + value%denom),
  // substitute into (value*numer)/denom and simplify.
  // r < denom, so (denom*numer) is the upper bound of (r*numer)
