I have the query SQL, :
SELECT tag, time, value, status
WHERE tag = 'sinusoid'
AND time BETWEEN '*-1h' AND '*'
Could you explain me how to get from the attribut "time" in query SQL :
- the Universal Coordinate Time (UTC) from the "time" in long / to January 1, 1970
- The timezone from the "time"
thank you for your reply..
