What does not work:
- Grafana's time shift option because it applies to all queries, and negative values not accepted.
- Adding 'offset' to the query allows to move it forward (to the right) in time, but a negative value is not accepted.
What does not work:
you may try offset modifier in promQL. However this will give you the right data with wrong (or confusing, because time offset is not applied to) timestamp.
