* Functions `toStartOfDay`, `toStartOfHour`, `toStartOfFifteenMinutes`, `toStartOfTenMinutes`, `toStartOfFiveMinutes`, `toStartOfMinute`, `timeSlot` return `DateTime` if their argument is a `Date` or `DateTime`, and they return `DateTime64` if their argument is a `Date32` or `DateTime64`.

## toUnixTimestampEx
Like `toUnixTimestamp`, converts a string, a date or a date with time to the [Unix Timestamp](https://en.wikipedia.org/wiki/Unix_time) in `Int64` representation.
If the function is called with a string, it accepts an optional timezone argument.
**Syntax**
``` sql
toUnixTimestampEx(date)
toUnixTimestampEx(str, [timezone])
```
**Returned value**
- Returns the unix timestamp. [UInt32](../data-types/int-uint.md).
**Example**
``` sql
SELECT
'1969-01-01 00:00:00' AS dt_str,
toUnixTimestamp(dt_str) AS from_str,
toUnixTimestampEx(dt_str) AS ex_str,
toUnixTimestamp(dt_str, 'Asia/Tokyo') AS from_str_tokyo,
toUnixTimestampEx(dt_str, 'Asia/Tokyo') AS ex_str_tokyo,
toUnixTimestamp(toDateTime(dt_str)) AS from_datetime,
toUnixTimestampEx(toDateTime64(dt_str, 0)) AS ex_datetime64
```
Result:
```
┌─dt_str──────────────┬─from_str─┬────ex_str─┬─from_str_tokyo─┬─ex_str_tokyo─┬─from_datetime─┬─ex_datetime64─┐
│ 1969-01-01 00:00:00 │ 0 │ -31564800 │ 0 │ -31568400 │ 0 │ -31564800 │

```
## toStartOfYear
Rounds down a date or date with time to the first day of the year. Returns the date as a `Date` object.
