how to set timer?

[prkumar]

What do yo by it does not work? You mean your handler does not get called?
If I were you I will attach gdb put a breakpoint at
ngx_event_timer.c::ngx_event_expire_timers and see that why at line number
149 ev->handler(ev); is not getting called.? For nginx debugging and figurng
things out nothing works better than gdb trust me.
