Go (golang) package for parsing time in Splunk's relative time syntax. See docs for format documentation, but here's some examples:
| Time | Description |
|---|---|
| -1m | One minute ago |
| +30m | 30 minutes from now |
| -4h@h | Four hours ago, snapped to the hour |
| -1week@week+1day | One week ago, snapped to Monday (1 day after Sunday, which is the default snap to) |
For details, see the API documentation.
