TZRELOAD(8) Maintenance Commands and Procedures TZRELOAD(8)

NAME

tzreload - notify timezone update

SYNOPSIS

tzreload [-a]

DESCRIPTION

The tzreload command triggers processes to reread timezone information.
The timezone information is cached in each process. In response to a
tzreload command, this cache is updated on the next call to ctime(3C)
and mktime(3C) by each process. By default, tzreload only triggers
this update for the current zone.

In addition to updating processes, the tzreload command also notifies
cron(8) to reinitialize the job scheduler with the new timezone
information.

OPTIONS

The following options are supported:

-a Update processes in all zones.

FILES

/usr/share/lib/zoneinfo
Standard zone information directory.

INTERFACE STABILITY

Committed

SEE ALSO

ctime(3C), mktime(3C), attributes(7), cron(8), zdump(8), zic(8),
zoneadm(8)

NOTES

Although tzreload reinitializes cron(8), applications that are affected
by timezone changes still need to be restarted or reinitialized if they
do not reread the new timezone information before timezone changes take
place.
