**Describe the bug**

```
    /// We count all hour-length intervals, unrelated to offset changes.
    inline time_t toRelativeHourNum(time_t t) const
    {
        if (t >= 0 && offset_is_whole_number_of_hours_during_epoch)
            return t / 3600;

        /// Assume that if offset was fractional, then the fraction is the same as at the beginning of epoch.
        /// NOTE This assumption is false for "Pacific/Pitcairn" and "Pacific/Kiritimati" time zones.
        return (t + DATE_LUT_ADD + 86400 - offset_at_start_of_epoch) / 3600 - (DATE_LUT_ADD / 3600);
    }

    template <typename DateOrTime>
    inline time_t toRelativeHourNum(DateOrTime v) const
    {
        return toRelativeHourNum(lut[toLUTIndex(v)].date);
    }

```
the code snippet is in DateLUTImpl.h 

lut[toLUTIndex(v)].date is Int64.
below is type define in mac OS.
```
typedef long long               int64_t;
typedef __darwin_time_t         time_t;
typedef long                    __darwin_time_t; 
```

function overload will cause  infinite loop

**Does it reproduce on recent release?**

It's a portability issue


**How to reproduce**

execute SQL on clickhouse which build on macOS

select toRelativeHourNum(toDate('2020-10-01'));

        Int64 guess = (t / 86400) + daynum_offset_epoch;

            --guess;
        if (guess < 0)
            return LUTIndex(0);
        if (guess >= DATE_LUT_SIZE)
            return LUTIndex(DATE_LUT_SIZE - 1);
        
        if (t >= lut[guess].date)
        {
            if (guess + 1 >= DATE_LUT_SIZE || t < lut[guess + 1].date)
                return LUTIndex(guess);
            return LUTIndex(guess + 1);
        }
