Subject: timeservers: Add Fallback Timerservers
X-Git-Tag: 2.0_alpha~456
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=920950231d5875220010ed5810593d42b0106dc2;p=framework%2Fconnectivity%2Fconnman.git

timeservers: Add Fallback Timerservers

Add Fallback timeservers via main.conf.

These timeservers are used for time corrections when
there are no valid timeservers provided by the user or by the
network. The list of timeservers which are queried for
timing correction are Timeservers.Configuration (set by the
user), service timeservers(via service), gateway, global
timeservers (via clock API) and fallback timeservers, in that order.
