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 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
