Input Stack: TimeSeriesExpr Duration

Output Stack: TimeSeriesExpr

Shift the time frame to use when fetching the data. This is used to look at a previous interval as a point of reference, e.g., day-over-day or week-over-week.

Examples:

Before	After	Combined
name,sps,:eq, (,name,),:by	name,sps,:eq, (,name,),:by, 1w,:offset	name,sps,:eq, (,name,),:by, :dup, 1w,:offset

Before	After	Combined
name,sps,:eq, (,name,),:by	name,sps,:eq, (,name,),:by, PT1H,:offset	name,sps,:eq, (,name,),:by, :dup, PT1H,:offset

Note that there is a deprecated List\[Duration\] variant that returns StyleExpr instead of TimeSeriesExpr and cannot be used with math operations.
