Updating the IANA Time Zone Database on Junos Devices
Junos devices use the tz database, also known as the IANA Time Zone Database to
manage time zones. This database is periodically updated by IANA to reflect political
and time changes. As such, you may need from time to time to update this file to ensure
the Junos devices continue to accurately reflect worldwide time zones and daylight
savings time intervals.
To update the IANA Time Zone Database, perform the following steps:
1.
Importing and Installing Time Zone Files on page 20
2.
Configuring a Custom Time Zone on page 21
Importing and Installing Time Zone Files
The IANA Time Zone Database is maintained by the Internet Assigned Numbers Authority
(IANA), which is a department of the Internet Corporation for Assigned Names and
Numbers (ICANN). You can download the latest IANA Time Zone Database file from the
following URL:
http://www.iana.org/time-zones .
The following steps will guide you through one method of installing the file to your device.
However, depending on your network access and other preferences, you may need to
modify these steps.
1.
Log into the Junos device.
2.
If you are in the CLI interface, open the shell interface.
device@user# start shell
3.
Create a
tz
directory in the
/var/tmp
and navigate to that directory.
# mkdir /var/tmp/tz
# cd /var/tmp/tz
4.
Using FTP, download the time zone files archive.
NOTE: FTP must be enabled on your device before you can use FTP. FTP
is enabled by adding the
ftp
statement into the
[edit system services]
hierarchy.
# ftp ftp.iana.org/tz
