    ntp: Fix second_overflow's input parameter type to be 64bits · c7963487
    DengChao authored
    The function "second_overflow" uses "unsign long"
    as its input parameter type which will overflow after
    year 2106 on 32bit systems.
    
    Thus this patch replaces it with time64_t type.
    
    While the 64-bit division is expensive, "next_ntp_leap_sec"
    has been calculated already, so we can just re-use it in the
    TIME_INS/DEL cases, allowing one expensive division per
    leapsecond instead of re-doing the divsion once a second after
    the leap flag has been set.
