NAME
       zdump - time zone dumper

SYNOPSIS
       zdump [-v] [-c cutoffyear] [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 GMT. This is consistent with the  behav-
       ior 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:

       -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 cutoffyear   Cuts off the verbose output near the start of the year cutoffyear.

EXIT STATUS
       The following exit values are returned:

       0	Successful completion.

       1	An error occurred.

FILES
