From 779d20892f8e716677194dc879eea2b5f1e75678 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 14 Nov 2007 16:58:29 -0800 Subject: rtc_hctosys expects RTCs in UTC (doc) The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local time (e.g. PST). Say so in Kconfig and in the kernel message. (Strictly speaking, the RTC clock should be tracking the POSIX epoch. That's not worth going into here. Goofing timezones means clocks are wrong by many hours; the POSIX-v-UTC differences just cost seconds.)
