rdate requires -s
Last modified: 2008-05-01 11:37:54 EDT
unlike every other unix, linux rdate requires -s to
set the date. argh.
I think this is a matter of preference, and there's no compelling reason to make
the change. I know at least a few times, I have been happy to be able to run
rdate without setting the system clock, so I could check the time on a system I
didn't have root on.
