[erlang-questions] Adding now + interval?

[zxq9]

Depending on what you are trying to do, it may be adequate to measure the 
result of a difference and compare the diff against some total amount, rather 
than adding to an existing timestamp and comparing.

Now = now(),
% ... some stuff
case timer:now_diff(now(), Now) > 500 of
% ...
