TimeRange

A context representing a period of time. Any user interfaces that represent or visualize events or activity over time can be filtered or focused on a particular time period, e.g.:

• A pricing chart
• A trade blotter
• A record of client contact/activity in a CRM

Example use cases:

• User may want to view pricing/trades/customer activity for a security over a particular time period, the time range might be specified as the context for the ViewChart intent OR it might be embedded in another context (e.g. a context representing a chart to plot).
• User filters a visualization (e.g. a pricing chart) to show a particular period, the TimeRange is broadcast and other visualizations (e.g. a heatmap of activity by instrument, or industry sector etc.) receive it and filter themselves to show data over the same range.

Notes:

• A TimeRange may be closed (i.e. startTime and endTime are both known) or open (i.e. only one of startTime or endTime is known).
• Ranges corresponding to dates (e.g. 2022-05-12 to 2022-05-19) should be specified using times as this prevents issues with timezone conversions and inclusive/exclusive date ranges.
• String fields representing times are encoded according to ISO 8601-1:2019.
  • A timezone indicator should be specified, e.g. "2022-05-12T15:18:03Z" or "2022-05-12T16:18:03+01:00"
  • Times MAY be specified with millisecond precision, e.g. "2022-05-12T15:18:03.349Z"
