Timers

timers.waitFor(duration) waits for a positive Helmr duration and timers.waitUntil(date) waits until an absolute JavaScript Date.

await timers.waitFor("30s")
await timers.waitUntil(new Date("2026-08-10T09:00:00Z"))

Both APIs return Promise<void> and are guest-runtime operations. Await them so the Run can durably park and resume. Durations use ms, s, m, h, or d.
