System Administration Commands                          zdump(1M)



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 GMTO. This is consistent
     with the behavior of the library calls; zdump  reflects  the
     same  behavior  of  the time routines 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  com-
                           puting  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 informa-
                           tion 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.
