Time series:
- return column named time_sec (UTC in seconds), use UNIX_TIMESTAMP(column)
- return column named value for the time point value
- return column named metric to represent the series name

Table:
- return any set of columns

Macros:
- $__time(column) -> UNIX_TIMESTAMP(column) as time_sec
- $__timeFilter(column) ->  UNIX_TIMESTAMP(time_date_time) ≥ 1492750877 AND UNIX_TIMESTAMP(time_date_time) ≤ 1492750877
- $__unixEpochFilter(column) ->  time_unix_epoch > 1492750877 AND time_unix_epoch < 1492750877
- $__timeGroup(column,'5m') -> (extract(epoch from "dateColumn")/extract(epoch from '5m'::interval))::int

Or build your own conditionals using these macros which just return the values:
- $__timeFrom() ->  FROM_UNIXTIME(1492750877)
- $__timeTo() ->  FROM_UNIXTIME(1492750877)
- $__unixEpochFrom() ->  1492750877
- $__unixEpochTo() ->  1492750877
