How can I tell how much time a program has been
running for in a perl script? I tried to do $time01 =
localtime() and $time02 = localtime() and then
subtract $time01 from $time02, but I always get zero,
even though there was about five or so minutes of
activity in between the parts where $time01 was
defined and $time02 was defined. My guess is that it
is not copying the variable over, but the memory
location, and since the variable within that memory
location is changing, both are changing, but this is
all just a guess...
So, does anyone know how I can tell how much time a
program has elapsed in perl?
