      <br>
          Thanks for your valuable reply and will consider your
      suggestion of using erlang:convert_time_unit/3 instead of assuming
      nanoseconds.<br>
      <br>

            <br>
            We are using "erlang:statistics(wall_clock)" to get the
            Erlang node up<br>
            time in millisecond.<br>
            <br>
            It works fine till 49 days, but on 49th day it will role
            back to start<br>
            from 0 millisecond.<br>
            <br>
            I need to know two things here, First of all, a different
            method for how<br>
            to test it, I don't want to wait for 49+ days to see it
            works or not.<br>
            <br>
            Secondly, I need to know a method which gives proper up time
            even after<br>
            49+ days. How about following:<br>
            <br>
            "(erlang:monotonic_time() - erlang:system_info(start_time))
            div 1000000000"<br>

          <div dir="auto">Apart from the assumption of nanosecond native
            time unit this is the way to do it. Use
            erlang:convert_time_unit() instead. There are Erlang systems
            not using nanoseconds as native time unit. </div>
