  Daylight savings time? (TCP/IP) 
 The Question is:
 
Is there a single coordinated daylight savings time change routine?
 
I did Utc$Configure_tdf.com.  I worked okay, changing the time and the
logical sys$timezone_differential.
 
The logicals  UCX$TDF, MCC_TDF, UCX$NTP_TZ  were not changed  (I haven't
looked at the C runtime library to see if that needs to be changed yet).
 
The NTP service set the time back to its previous value! (vms 7.1 ucx 4.2)
 
It looks like I have to:
1) stop NTP
2) do utc$configure_tdf.com
3) change MCC_TDF, UCX$DF, and UCX$NTP_TZ.
4) restart NTP.
(did I miss anything?)
 
Thanks
Jim
 
 The Answer is:
 
  You will want to remove the UCX$NTP_TZ logical name definition;
  review SYS$MANAGER:UCX$NTPD_STARTUP.COM or TCPIP$NTPD_STARTUP
  for details, and review the TCP/IP Services Management manual
  looking for configuration information.
 
  C and the C library are based on the OpenVMS UTC calls.
 
  Also review the NTP logs -- UCX$NTP.LOG or TCPIP$NTP.LOG, depending
  on the version of TCP/IP Services for OpenVMS.
