currentTime (Function)

Function returns system time in HH:mm:ss format.

Syntax​

<STRING> time:currentTime()

Query Parameters​

None

Example 1​

@info(name = 'currentTimeExample')
SELECT time:currentTime() AS currentTime;

The currentTimeExample demonstrates the use of the time:currentTime() function to get the current system time in the HH:mm:ss format. The function returns a string representing the current time, such as 14:21:26.

Example 2​

CREATE STREAM InputStream (eventTime long);
CREATE SINK STREAM OutputStream (eventTime long, currentTime string);

@info(name = 'currentTimeStreamWorker')
INSERT INTO OutputStream
SELECT eventTime, time:currentTime() AS currentTime
FROM InputStream;

The currentTimeStreamWorker processes events from the InputStream and uses the time:currentTime() function to get the current system time in the HH:mm:ss format. The query outputs the eventTime and a string representing the current time as the currentTime attribute for each event to the OutputStream.
