Time offsets

Estimation and validation as well as other calculations often need to reference data from a different time period. Specify time offsets by adding an offset argument to the end of the service point channel reference. For example, A:1[-1 da] means the value from channel A:1 one day ago. Options for offsets include:

• Intervals [+/- N]

• HM [+/- NH:M]

• Days [+/- Nda]

• Weeks [+/- Nwk]

• Years [+/- Nyr]
