Usage Guidelines for Setting a Custom Time Zone

To use a custom time zone, follow these steps:

1. Download a time zones archive (from a known or designated source) to the router. Compile the time zone archive using the zic time zone compiler, which generates tz files.
2. Using the CLI, configure the router to enable the use of the generated tz files as follows:

   [edit]
   user@host# set system use-imported-time-zones
   

3. Display the imported time zones (saved in the directory /var/db/zoneinfo/):

   [edit] 
   user@host# set system time-zone ?
   

   If you do not configure for using imported time zones, the JUNOS default time zones are shown (saved in the directory /usr/share/zoneinfo/).
