Newer installworld_nk script (64-bit time_t)

[Harti Brandt]

Hi,

your script looks fine, although I could not test it - I just have no time
at the moment to re-create a 32-bit time_t version on my sparc. I'd say
its time now to through the switch. I recommend, however, to give re a
hint that this is going to happen - they'll surely want to know this :-)

Nice work, thanks,

harti
