Which "it"?  Output from 'date' or the HWclock contents?

Do you reboot between the time you set the HWclock, and the instant you
find UTC showing up somewhere?

If so, what is the contents of your /etc/hardwareclock file?

Since you say you are not running windows, then quit trying to store
the hardware clock as localtime, have it set to UTC, and everything
will be fine.  You'll still see localtime everywhere anyway.

If /etc/hardwareclock already say UTC, leave it alone.  If not, change
"localtime" to UTC in the file, and quit trying to have the HWclock be
local.

Then, set the system time if/when you need to adjust things (use the
date command, it also "sets/changes" the time).  And then save the
result into the hardware clock with:

  hwclock --utc --systohc

Or, setup an ntp client to keep your clocks synced with the ntp system
on the internet, and just let the Slackware 14.1 rc.d scripts save the
system time to the hardware clock when you do shutdown.

Just always give the 'hwclock' command the --utc flag and it will
translate the time from the hwclock into your local time for you when
you want to view/reset the hwclock.
