NAME
      zdump - time zone dumper
 


SYNOPSIS
      zdump [ -v ]  [ -c cutoffyear ]  [ zonename ... ]
 


DESCRIPTION
      The zdump command prints the current time for each  timezone
      (zonename)  listed  on the command line. Specify zonename as
      the  name  of  the  timezone  database  file   relative   to
      /usr/share/lib/zoneinfo.
 
      Specifying an invalid timezone (zonename) to  zdump does not
      return  an  error,   rather   zdump  uses GMT.  This is con-
      sistent 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:
 
      -v    Displays the entire contents of the timezone  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  com-
            puting local time change, the time at the highest pos-
            sible 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  other-
            wise.
 
      -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.
