Re: [PATCH] hwclock: flush stdout in hwclock -c

[J William Piggott <elseifthen@gmx.com>]

Hello Alexey,

 I've been advocating for the removal of the compare function. One of my
 justifications for doing so is that it has been broken from day one and
 therefore nobody can be using for anything.

 So could you tell me how you are using it, and what useful purpose it is
 serving for you?

Thanks
 William
