    NAME
           zdump - time zone dumper
    
    SYNOPSIS
           zdump [--version] [-v] [-c [loyear,]hiyear] [zonename]...
    
    
    DESCRIPTION
           The zdump command prints	the current time for each time zone (zonename)
           listed on the command line. Specify zonename as the name	 of  the  time
           zone database file relative to /usr/share/lib/zoneinfo.
    
    
           Specifying  an invalid time zone	(zonename) to zdump does not return an
           error, rather zdump uses	UTC. This is consistent	with the  behavior  of
           the  library  calls;  zdump reflects the	same behavior of the time rou-
           tines in	libc. See ctime(3C) and	mktime(3C).
    
    OPTIONS
           The following options are supported:
    
           --version	     Outputs version information and exits.
    
    
           -v		     Displays the entire contents  of  the  time  zone
    			     database  file  for  zonename. Prints the time at
    			     the lowest	possible time value; the time one  day
    			     after  the	 lowest	possible time value; the times
    			     both one second before and	exactly	at  each  time
    			     at	 which	the  rules  for	 computing  local time
    			     change; the time at  the  highest	possible  time
    			     value;  and  the  time  at	 one day less than the
    			     highest possible time value. See  mktime(3C)  and
    			     ctime(3C)	for  information  regarding time value
    			     (time_t). Each line of output ends	 with  isdst=1
    			     if	 the  given  time  is Daylight Saving Time, or
    			     isdst=0 otherwise.
    
    
           -c [loyear],hiyear    Cuts off the verbose output near the start	of the
    			     given  year(s) . By default, the program cuts off
    			     verbose output near the start of the  years  -500
    			     and 2500.
