- $__timeEpoch -> extract(epoch from column) as "time"
- $__timeFilter(column) -> extract(epoch from column) BETWEEN 1492750877 AND 1492750877
- $__unixEpochFilter(column) -> column > 1492750877 AND column < 1492750877
- $__timeGroup(column,'5m') -> (extract(epoch from "dateColumn")/300)::bigint*300
- $__timeGroup(column,'5m') -> (extract(epoch from column)/300)::bigint*300 AS time
Example of group by and order by with $__timeGroup:
SELECT
$__timeGroup(date_time_col, '1h') AS time,
$__timeGroup(date_time_col, '1h'),
sum(value) as value
FROM yourtable
GROUP BY time
