If `expr` is a number, it is interpreted as the number of seconds since the beginning of the Unix Epoch (as Unix timestamp).
If `expr` is a [String](../data-types/string.md), it may be interpreted as a Unix timestamp or as a string representation of date / date with time.

If `expr` is a [String](../data-types/string.md), it may be interpreted as a Unix timestamp or as a string representation of date / date with time.
Thus, parsing of short numbers' string representations (up to 4 digits) is explicitly disabled due to ambiguity, e.g. a string `'1999'` may be both a year (an incomplete string representation of Date / DateTime) or a unix timestamp. Longer numeric strings are allowed.

## toUnixTimestamp64Second
Converts a `DateTime64` to a `Int64` value with fixed second precision. The input value is scaled up or down appropriately depending on its precision.
:::note
The output value is a timestamp in UTC, not in the timezone of `DateTime64`.
:::
**Syntax**
```sql
toUnixTimestamp64Second(value)
```
**Arguments**
- `value` — DateTime64 value with any precision. [DateTime64](../data-types/datetime64.md).
**Returned value**
- `value` converted to the `Int64` data type. [Int64](../data-types/int-uint.md).
**Example**
Query:
```sql
WITH toDateTime64('2009-02-13 23:31:31.011', 3, 'UTC') AS dt64
SELECT toUnixTimestamp64Second(dt64);

```
## toUnixTimestamp64Micro
Converts a `DateTime64` to a `Int64` value with fixed microsecond precision. The input value is scaled up or down appropriately depending on its precision.
