timestampInMilliseconds (Function)

Returns the system time or the given time in milliseconds.


<LONG> time:timestampInMilliseconds()
<LONG> time:timestampInMilliseconds(<STRING> date.value, <STRING> date.format)
<LONG> time:timestampInMilliseconds(<STRING> date.value)

Query Parameters

NameDescriptionDefault ValuePossible Data TypesOptionalDynamic
date.valueThe value of the date. For example, 2014-11-11 13:23:44.657, 2014-11-11, 13:23:44.657.Current system timeSTRINGYesYes
date.formatThe format of the date value provided. For example, yyyy/MM/dd HH:mm:ss.SSS.yyyy-MM-dd HH:mm:ss.SSSSTRINGYesYes

Example 1

SELECT time:timestampInMilliseconds() AS currentTimeMillis;

This query returns the system current time in milliseconds.

Example 2

SELECT time:timestampInMilliseconds('2007-11-30 10:30:19', 'yyyy-MM-dd HH:mm:ss') AS millis;

This query converts the timestamp string '2007-11-30 10:30:19' in the format 'yyyy-MM-dd HH:mm:ss' to milliseconds. The output is 1196418619000.

Example 3

SELECT time:timestampInMilliseconds('2007-11-30 10:30:19.000') AS millis;

This query converts the timestamp string '2007-11-30 10:30:19.000' in the format 'yyyy-MM-dd HH:mm:ss.SSS' to milliseconds. The output is 1196418619000.

Example 4

CREATE STREAM InputStream (timestampStr string, format string);
CREATE SINK STREAM OutputStream (millis long);

@info(name = 'timestampInMillisecondsQuery')
INSERT INTO OutputStream
SELECT time:timestampInMilliseconds(timestampStr, format) AS millis
FROM InputStream;

The timestampInMillisecondsQuery processes events from the InputStream, which contains a timestamp string (timestampStr) and its corresponding format (format). It uses the time:timestampInMilliseconds(timestampStr, format) function to convert the timestamp string in the specified format to milliseconds. The query outputs the converted value as the millis attribute for each event to the OutputStream.
