historyFrom

HistoryFrom is a term used in computing and data management to denote the starting point from which historical data should be considered or retrieved. It is not a universal standard with a single defined meaning; instead it functions as a label, parameter, or function name whose exact behavior depends on the context or software system.

In data querying and time-series databases, historyFrom typically specifies a timestamp or date from which records are returned. For example, a query or API call may include historyFrom='2023-01-01T00:00:00Z' to fetch events starting at that moment.

In user interfaces, a control labeled History from may allow users to filter displayed data to a chosen start date, effectively trimming the visible history to a window defined by that date and possibly an end date.

In programming libraries, historyFrom can be a function or property name in camelCase (historyFrom) or PascalCase (HistoryFrom). Its semantics may be to compute a rolling history window, initialize a data stream, or return a subset of historical records.

Notes: Because the term is not standardized, developers should consult the specific documentation for the system in question to determine the precise meaning, data types, and timezone considerations. It is often used alongside related terms such as historyTo, startDate, and window.
