| Field | Type | Description |
|---|---|---|
| fixed_time_range | [bitdrift.public.unary.common.v1.TimeRange.FixedTimeRange](#bitdrift.public.unary.common.v1.TimeRange.FixedTimeRange "bitdrift.public.unary.common.v1.TimeRange.FixedTimeRange")only one of fixed_time_range, or relative_time_range can be set | A fixed time range with explicit start and end times. This will ignore any look back delay settings. |
| relative_time_range | [bitdrift.public.unary.common.v1.TimeRange.RelativeTimeRange](#bitdrift.public.unary.common.v1.TimeRange.RelativeTimeRange "bitdrift.public.unary.common.v1.TimeRange.RelativeTimeRange")only one of relative_time_range, or fixed_time_range can be set | A relative time range, defined as a duration back from 'now', minus any look back delay. If this is 15 minutes, and the lookback delay is 5 minutes, this represents the time range from 20 minutes ago to 5 minutes ago. |
Example
```json
{
"relative_time_range": {
"duration": "3600s",
"offset": "3600s"
}
}
