Prefer comparisons in the `absl::Time` domain instead of the integer domain.

N.B.: In cases where an `absl::Time` is being converted to an integer, alignment may occur. If the comparison depends on this alignment, doing the comparison in the `absl::Time` domain may yield a different result. In practice this is very rare, and still indicates a bug which should be fixed.

Examples:

    // Original - Comparison in the integer domain
    int x;
    absl::Time t;
    if (x < absl::ToUnixSeconds(t)) ...

    // Suggested - Compare in the absl::Time domain instead
    if (absl::FromUnixSeconds(x) < t) ...
