dtimer

Distributed timer backed by Redis for clustered server environments. Version 0.3.3 (stable; low release cadence). Replaces unreliable setTimeout() with persistent timed events stored in Redis, supporting round-robin distribution across multiple listeners via pubsub. Requires Redis 2.6.0+ and promisified redis client (bluebird). Key differentiator: low-latency notification and retry mechanism via confirmation timeout.
