编译：

[root@slayer poco]# g++ timer.cc -lPocoFoundation

结果：

[root@slayer poco]# ./a.out
onTimer called.
[root@slayer poco]# ./a.out 1000 600
onTimer called.
onTimer called.
[root@slayer poco]# ./a.out 1500 100
onTimer called.
onTimer called.
onTimer called.
onTimer called.
onTimer called.
onTimer called.
