-/**
- * This module offers an optimized timer implementation designed for scenarios
- * where high precision is not critical.
- *
- * The timer achieves faster performance by using a low-resolution approach,
- * with an accuracy target of within 500ms. This makes it particularly useful
- * for timers with delays of 1 second or more, where exact timing is less
- * crucial.
- *
- * It's important to note that Node.js timers are inherently imprecise, as
- * delays can occur due to the event loop being blocked by other operations.
- * Consequently, timers may trigger later than their scheduled time.
