Thanks for the reply chrysn,
I am using No OS, I have inserted LwIP code into stm32L using IAR compiler, my sys_now() is working fine as I am using Hardware Timer(Systick timer) and it is producing proper milliseconds.
The problem--> sys_timeout() was calling handler function immediately. Is fixed now.
I have now fixed the problem using sys_restart_timeouts() before sys_timeout(), sys_restart_timeouts() sets back the timestamp of the last call to sys_check_timeouts(). Thus after 1000 milliseconds, I get called the handler function (Just what I needed).
I am using this timeout in getting Request Timeout prints in ping.c.

what are you using to handle timeouts? do you use an operating system
(which?) or are you in NO_SYS=1 mode? if NO_SYS=1, is your sys_now()
function reliably producing milliseconds?
