	...args: any
): boolean;

Example

// 1. 设置每 200ms 触发一次的循环定时器，统计触发次数
let tickCount = 0;
const created = eda.sys_Timer.setIntervalTimer('嘉立创示例_循环', 200, () => { tickCount++; });

// 2. 让它运行约 1.5 秒
await new Promise(resolve => setTimeout(resolve, 1500));
const ticksAtClear = tickCount;

// 3. 用完清除，定时器停止（净零收尾，可重复运行）
const cleared = eda.sys_Timer.clearIntervalTimer('嘉立创示例_循环');

// 4. 再等一会，确认清除后没有继续触发
await new Promise(resolve => setTimeout(resolve, 600));

console.log('设置结果：', created);
console.log('清除结果：', cleared);
console.log('运行期间触发次数：', ticksAtClear, '，清除后新增：', tickCount - ticksAtClear);
