NAME

     zdump -- timezone dumper

SYNOPSIS

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

DESCRIPTION

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

     The following 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 possible
	     time value, the times both one second before and exactly at each detected time discontinuity, the time at one day less than the high-
	     est 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,hiyear
	     Cut off 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.

       zdump - timezone dumper

SYNOPSIS

       zdump [ --version ] [ --help ] [ -v ] [ -c [loyear,]hiyear ] [ 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.

       --help Output short usage 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 possible
	      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 Day-
	      light Saving Time or isdst=0 otherwise.

       -c [loyear,]hiyear
	      Cut off the verbose output near the start of the given year(s).  The output still includes the lowest possible time  value  and  one
	      day after it, and the highest possible time value preceded by the time value one day before it.
