Time Zone Considerations

On HP-UX systems, the icapd daemon performs routine Instant Capacity software tasks on a daily basis. A partition’s local time zone setting affects what time zone the icapd daemon uses for the timing of these tasks Be sure that the time zone is set properly to ensure synchronization among the partitions.

Because the HP-UX icapd daemon is started by init, the /etc/default/tz file must contain the desired time zone specification. By default, the time zone is set to EST5EDT. You can specify the time zone the icapd daemon uses to interpret noon and midnight by modifying the entry in the /etc/default/tz file.

On OpenVMS systems, the ICAP_SERVER uses the time zone settings defined by the

SYS$STARTUP:TDF$UTC_STARTUP.COM file. To view the time zone settings, enter the command @sys$manager:utc$time_setup “show”. Enter the command @sys$manager:utc$time_setup and follow the menu instructions to modify the time zone setting for the iCAP partition.
