# now

[Read this page in HTML](https://www.scopedb.io/docs/reference/functions/date-and-time/now)

Returns the current query timestamp.

## Syntax

```scopeql
now()
```

## Arguments

None.

## Returns

Returns `timestamp`. The value is fixed for the query and represents an instant in UTC, with nanosecond precision.

## Examples

Select events from the last 15 minutes:

```scopeql
VALUES
    (now() - 'PT2m'::interval, 'payment_failed'),
    (now() - 'PT8m'::interval, 'checkout_started'),
    (now() - 'PT20m'::interval, 'cart_viewed')
SELECT $0 AS event_time, $1 AS event
WHERE event_time >= now() - 'PT15m'::interval
SELECT event, now() - event_time AS age
ORDER BY age
```

```text
+------------------+------+
| event            | age  |
+------------------+------+
| payment_failed   | 2m0s |
| checkout_started | 8m0s |
+------------------+------+
```

Every `now()` in this statement uses the same query instant, so the cutoff and calculated ages are consistent.
