Trigger time report

// Purpose: the script of a Time Trigger Line: when the market clock reaches the
// line, report the workspace — what it is looking at when that time comes.
// Category: workspace
// Permissions: workspace.read
// Preconditions: set as the script of a Time Trigger Line, with
// workspace.read ticked on its Trigger page
// Side effects: none (read-only)
// Run: place a Time Trigger Line, open its properties, Trigger page:
// Choose… this file, tick workspace.read, and set it to fire in Replay or
// Both to watch it arrive in a replay.
