ZDUMP(8)                NetBSD System Manager's Manual                ZDUMP(8)

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
                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 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 val-
     ues that are neither float nor double.

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