For stretches when none is open, it adds up processor time (how long the computer's processor spent working for Claude Code) and elapsed clock time.\n\n**Why**\n\nThis is internal measurement only. It adds nothing you can turn on or change.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
