NAME

     zdump -- time zone dumper

SYNOPSIS

     zdump [--version] [-v] [-c [loyear,]highyear] [zonename ...]

DESCRIPTION

     zdump prints the current time in each zonename named on the command line.

     These options are available:
     --version	Output version information and exit.
     -v 	For each zonename on the command line, print the time at the lowest possible time value, the time one day after the lowest possi-
		ble time value, the times both one second before and exactly at each detected time discontinuity, the time at one day less than
		the highest possible time value, and the time at the highest possible time value, Each line ends with
		      isdst=1
		if the given time is Daylight Saving Time or
		      isdst=0
		otherwise.
     -c [loyear,]highyear
		Cut off the verbose output near the start of the given year(s).  By default, the program cuts off verbose output near the starts
		of the years -500 and 2500.

LIMITATIONS

     The -v option may not be used on systems with floating-point time_t values that are neither float nor double.

     Time discontinuities are found by sampling the results returned by localtime at twelve-hour intervals.  This works in all real-world cases;
     one can construct artificial time zones for which this fails.

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
