From b149ee2233edf08fb59b11e879a2c5941929bcb8 Mon Sep 17 00:00:00 2001 From: john stultz Date: Tue, 6 Sep 2005 15:17:46 -0700 Subject: [PATCH] NTP: ntp-helper functions This patch cleans up a commonly repeated set of changes to the NTP state variables by adding two helper inline functions: ntp_clear(): Clears the ntp state variables ntp_synced(): Returns 1 if the system is synced with a time server. This was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc, sparc64.
