On VMS 7.3-1 doesn't Multinet work with the sysgen parameter
AUTO_DLIGHT_SAV ?

SYSGEN> HELP SYS_PAR AUTO_DLIGHT_SAV

Sys_Parameters

  AUTO_DLIGHT_SAV

       AUTO_DLIGHT_SAV is set to either 1 or 0. The default is 0.

       If AUTO_DLIGHT_SAV is set to 1, OpenVMS automatically makes the
       change to and from daylight saving time.
