Subject: ntpclient: initial frequency offset configuration and adjtimex invocation
X-Git-Url: http://207.154.207.93/?a=commitdiff_plain;h=9c06902921e32182fd3925abf26ac06c20e3dbde;p=packages.git

ntpclient: initial frequency offset configuration and adjtimex invocation

This adds a new config file section "ntpdrift" to /etc/config/ntpclient
to support setting an initial value "freq" for frequency offset.
Changes /etc/hotplug.d/iface/20-ntpclient to call adjtimex
and do an initial frequency offset before starting ntpclient.
