Sample

install and advance timers using FakeTimers clock

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. FakeTimers.install replaces global timer functions and initializes now to the configured timestamp
  2. clock.tick advances time and triggers scheduled setTimeout callbacks synchronously
  3. clock.tick handles repeating setInterval callbacks and stops after clearInterval
  4. clock.runAll executes all scheduled timers until the queue is empty
  5. clock.setSystemTime adjusts current clock time without executing intermediate scheduled timers
  6. FakeTimers.createClock creates an isolated clock instance without mutating globals
  7. clock.uninstall restores all overridden globals cleanly
