Coexistence Issues
If you have NetWare servers earlier than version 5.1, you need to install at least one later version
NetWare server to bridge between the TIMESYNC NLM on the earlier server and any OES 2
servers you have on your network. This is because the earlier versions of Timesync can't consume
or provide NTP time packets and the xntpd daemon on Linux can't provide or consume Timesync
packets.
Fortunately, the TIMESYNC NLM in NetWare 5.1 and later can both consume and provide
Timesync packets. And the XNTPD NLM can provide Timesync packets when required.
This is explained in "Compatibility with Earlier Versions of NetWare" on page
Upgrading from NetWare to OES 2
The OES 2 SP3 Migration Tool can migrate time synchronization services from NetWare to Linux.

eDirectory gets its time synchronization information from the host
