R devel - May 2002 - converting #sec to POSIX* format

Sure I'm missing something simple here, but I haven't been able to find
a
easy way to convert a pure numeric (# of seconds since the beginning of
1970) back into a POSIX* object. 

ex.
> z<-as.POSIXct(Sys.time()) 
> z
[1] "2002-05-01 10:33:56 Mountain Daylight
Time"
> x<-unclass(z)
> x
[1] 1020270836

Is there a simple way to transform x back into a POSIX* object similar to z?
