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.


EXIT STATUS
       The following exit values are returned:

       0    Successful completion.


       1    An error occurred.


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