Subject: [PATCH] rtc: Don't state that the RTC holds UTC in case it doesn't
Date:   Fri, 21 Jun 2019 11:51:26 +1000
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some machines store local time in the Real Time Clock. The hard-coded
"UTC" string is wrong on those machines so just omit that string.
Update the log parser so it doesn't require the string "UTC".
