settz(8)settz(8)NAMEsettz - Set system time zone information.
SYNOPSIS
/usr/sbin/settz
DESCRIPTION
The settz command sets the system time zone information, based on the
current /etc/zoneinfo database configuration. If the /etc/zoneinfo
database is not configured, it sets the system time information as if
the database is configured to a Coordinated Universal Time (UTC)
default.
The settz command does the following: Calls tzset() to get current
default time zone information Ignores the TZ environment variable if a
value is set for TZ Creates a struct timezone with time zone offset,
and daylight savings information Calls settimeofday()
The current system date and time are not changed.
This command runs automatically when the system is entering a multiuser
run level. You should use it whenever you change the default time zone
information with the zic command.
NOTES
You must have superuser (root) privileges to use this command.
