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.

-
- ModernFakeTimers
- Environment
- node 22.23.2
- Created
- 2026-08-23T16:20:35Z
Contract
- ModernFakeTimers instantiates with global environment and intercepts timer functions upon useFakeTimers and restores original implementations on useRealTimers
- advanceTimersByTime advances virtual clock by milliseconds and fires scheduled timer callbacks synchronously
- advanceTimersByTimeAsync advances virtual clock asynchronously and resolves pending asynchronous timer callbacks
- advanceTimersToNextTimer and advanceTimersToNextTimerAsync progress virtual time directly to the earliest scheduled timer
- runAllTimers and runAllTimersAsync exhaustively execute all queued and recursively scheduled timers
- runOnlyPendingTimers and runOnlyPendingTimersAsync execute currently queued timers without running newly scheduled nested timers
- clearAllTimers and getTimerCount track and cancel active scheduled timers
- setSystemTime, now, and reset manage and simulate current timestamp
- runWithFakeTime helper safely executes a scoped callback and restores native timers
