Timesync Directory Tree Mode and DNS-rooted Trees

You must take care to ensure that time synchronization is configured correctly when you use Timesync Directory Mode in conjunction with multiple DNS-rooted trees.

Currently, all first servers in each DNS-rooted tree will be set to SINGLE reference time servers. If this is not changed, timesync will have problems because multiple servers will then advertise as the SINGLE reference time source for the DNS tree.

If you do use SINGLE reference servers, you must either turn off Directory Tree Mode and then use Configured Time Sources, or you need to make sure only one server is a SINGLE reference time source.

If you are using Directory Tree Mode and you install the Nth server into a DNS-rooted tree, the timesync setup automatically makes this server a SECONDARY time source. Timesync also adds a TIMESOURCE line to the TIMESYNC.CFG file with the name of the root-most master server of the current tree. You may need to remove this if your master is not a SINGLE, PRIMARY or REFERENCE time source for your DNS-rooted tree.
