TCPIP supports NTP version 3, see:
http://www.openvms.compaq.com:8000/72final/6526/6526profile_contents_002.html#toc_chapter_10
The configuration is done in: SYS$SPECIFIC:[TCPIP$NTP]TCPIP$NTP.CONF
I just added different time sources in Germany like:

server ptbtime1.ptb.de
server ptbtime2.ptb.de
server ntp.fhg.de
server noc.belwue.de

the service is activated using $@SYS$MANAGER:TCPIP$CONFIG.COM.
So I'm getting the time using NTP and I'm distributing the time to our
Digital systems using DTSS. One system acts as DTSS server the other
systems are DTSS clients.
DTSS is configured with $@SYS$MANAGER:DTSS$CONFIG.COM. For your DTSS
server you have to copy the file SYS$MANAGER:NET$DTSS_CLERK_STARTUP.NCL
to SYS$MANAGER:NET$DTSS_SERVER_STARTUP.NCL and to modify:

!
! N E T $ D T S S _ S E R V E R _ S T A R T U P . N C L
!
! 30-MAR-2000
! I copied SYS$COMMON:[SYSMGR]NET$DTSS_CLERK_STARTUP.NCL;1 to this file
and changed clerk to server
! The command procedure SYS$STARTUP:DTSS$STARTUP.COM looks for server
first.
! So the node acts as DTSS time server.
!
! Create DTSS
!
!CREATE DTSS TYPE CLERK
!
CREATE DTSS TYPE SERVER
!
! Enter any user specific configuration directives
! here, before the issue of the ENABLE directive.
!
! Start DTSS and set the clock if  the first synchronization succeeds
!
ENABLE DTSS SET CLOCK TRUE
!
!+
! Add Any Commands Below this comment:
!-
! 30-MAR-2000
! OPCOM message: "to few servers detected" is turned off with the next
command
!
SET DTSS SERVERS REQUIRED 1
 

Check your systems with $SHOW SYSTEM/PROCESS=*DTSS* to see if the DTSS
process is running.
