[erlang-questions] Unexpected behaviour of timer:sleep

[shehan]

timer:sleep(1) means 1 millisecond hold the process. But 15000 mean 15
milliseconds.  In old Erlang version (5.5.5) it is came as expected.(pls see
below)  15000 come in Erlang 5.6 version. 

 

In Erlang 5.5.5

==========

1> timer:tc(timer, sleep, [1]).
{1643,ok}
2> timer:tc(timer, sleep, [2]).
{2553,ok}
3> timer:tc(timer, sleep, [7]).
{7393,ok}

Hi all,

When I am running following command, unexpected value came as result. Why is
that??

 

(test@REDACTED)15> timer:tc(timer, sleep, [1]).  

{15000,ok}

I expected value is, between 1000 to 2000.


timer:tc returns the elapsed time in microseconds, so it is within your
expectation!
