RTFM.

From the man page on date
---------------
 -u, --universal

Print or set the time and date in Coordinated  Universal 
Time (also known as Greenwich Mean Time) instead of in
local (wall clock) time.

From the man page on hwclock
-------------
 --utc  
 
Indicates that the Hardware Clock is kept  in  Universal
Coordinated Time.  It is your choice whether to keep your
clock in UTC or local time, but  nothing  in  the  clock 
tells which you've chosen.  So this option is how you  give 
that information  to hwclock.
