zdump(1M)

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 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 time zone database
           file  for zonename. Prints the time at the lowest pos-
           sible 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.
