回复: Re: [chrony-dev] Issue about chronyd synchronize to local clock

[saga m <xqmeng80@xxxxxxxxxxx>]

The 'local' directive is a server feature, not client's, so that won't
work. If you have installed adjtimex, you could use it to clear the
unsynchronized status periodically with "adjtimex -S 0 -m 0". No need
to run an NTP server/client.

  When will the kernel set the unsychronized status again, it seems that I have to excute 'adjtimex -S 0 -m 0' periodically as you mentioned  

  otherwise the unsynchronized status will set back again.

An application requires accurate system clock, and you are trying to
force it to run even when the clock is not synchronized?

The 'local' directive is a server feature, not client's, so that won't
work. If you have installed adjtimex, you could use it to clear the
unsynchronized status periodically with "adjtimex -S 0 -m 0". No need
