## UUIDv7ToDateTime
|
||||
|
||||
Returns the timestamp component of a UUID version 7.
|
||||
|
||||
**Syntax**
|
||||
|
||||
``` sql
|
||||
UUIDv7ToDateTime(uuid[, timezone])
|
||||
```
|
||||
|
||||
**Arguments**
|
||||
|
||||
- `uuid` — [UUID](../data-types/uuid.md) of version 7.
|
||||
- `timezone` — [Timezone name](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-timezone) for the returned value (optional). [String](../../sql-reference/data-types/string.md).
|
||||
|
||||
**Returned value**
|
||||
|
||||
- Timestamp with milliseconds precision. If the UUID is not a valid version 7 UUID, it returns 1970-01-01 00:00:00.000.
|
||||
|
||||
Type: [DateTime64(3)](/docs/en/sql-reference/data-types/datetime64.md).
|
||||
|
||||
**Usage examples**
|
||||
|
||||
``` sql
|
||||
SELECT UUIDv7ToDateTime(toUUID('018f05c9-4ab8-7b86-b64e-c9f03fbd45d1'))
|
||||
```
|
||||
|
||||
Result:
|
||||
|
||||
```response
|
||||
┌─UUIDv7ToDateTime(toUUID('018f05c9-4ab8-7b86-b64e-c9f03fbd45d1'))─┐

|
||||
```

## serverUUID()
|
||||
|
||||
Returns the random UUID generated during the first start of the ClickHouse server. The UUID is stored in file `uuid` in the ClickHouse server directory (e.g. `/var/lib/clickhouse/`) and retained between server restarts.
