:) SELECT toUInt64(toDateTime('2018-01-02 12:12:22'));

SELECT toUInt64(toDateTime('2018-01-02 12:12:22'))

┌─toUInt64(toDateTime('2018-01-02 12:12:22'))─┐
│                                  1514884342 │

My query returns a different result

SELECT toUInt64(toDateTime('2018-01-02 12:12:22', 'UTC'))

┌─toUInt64(toDateTime('2018-01-02 12:12:22', 'UTC'))─┐
│                                         1514895142 │
└────────────────────────────────────────────────────┘
