Hi all,

We are using "erlang:statistics(wall_clock)" to get the Erlang node up 
time in millisecond.

It works fine till 49 days, but on 49th day it will role back to start 
from 0 millisecond.

I need to know two things here, First of all, a different method for how 
to test it, I don't want to wait for 49+ days to see it works or not.

Secondly, I need to know a method which gives proper up time even after 
49+ days. How about following:

"(erlang:monotonic_time() - erlang:system_info(start_time)) div 1000000000"

If any one having more insight on this, please shed some light on these 
topics.

Thanks and regards,

Mithun B
