   3 NAME
   4      tzreload - notify timezone update
   5 
   6 SYNOPSIS
   7      tzreload [-a]
   8 
   9 DESCRIPTION
  10      The tzreload command triggers processes to reread timezone information.
  11      The timezone information is cached in each process.  In response to a
  12      tzreload command, this cache is updated on the next call to ctime(3C) and
  13      mktime(3C) by each process.  By default, tzreload only triggers this
  14      update for the current zone.
  15 
  16      In addition to updating processes, the tzreload command also notifies
  17      cron(1M) to reinitialize the job scheduler with the new timezone
  18      information.

  36 NOTES
  37      Although tzreload reinitializes cron(1M), applications that are affected
  38      by timezone changes still need to be restarted or reinitialized if they
  39      do not reread the new timezone information before timezone changes take
  40      place.
