[erlang-questions] Timezone calculations

[Kenji Rikitake]

Starting from an external program connected with Erlang by the port
function looks much safer than making a linked driver.

BTW Perl CPAN has DateTime library.  It works for many different
conversion requests, including the TAI issues I worked recently.
