NAME

6       zdump - time zone dumper

SYNOPSIS

9       zdump [--version] [-v] [-c [loyear,]hiyear] [zonename]...
10
11

DESCRIPTION

13       The zdump command prints the current time for each time zone (zonename)
14       listed on the command line. Specify zonename as the name  of  the  time
15       zone database file relative to /usr/share/lib/zoneinfo.
16
17
18       Specifying  an invalid time zone (zonename) to zdump does not return an
19       error, rather zdump uses GMTO. This is consistent with the behavior  of
20       the  library  calls;  zdump reflects the same behavior of the time rou‐
21       tines in libc. See ctime(3C) and mktime(3C).

OPTIONS

24       The following options are supported:
25
26       --version             Outputs version information and exits.
27
28
29       -v                    Displays the entire contents  of  the  time  zone
30                             database  file  for  zonename. Prints the time at
31                             the lowest possible time value; the time one  day
32                             after  the  lowest possible time value; the times
33                             both one second before and exactly at  each  time
34                             at  which  the  rules  for  computing  local time
35                             change; the time at  the  highest  possible  time
36                             value;  and  the  time  at  one day less than the
37                             highest possible time value. See  mktime(3C)  and
38                             ctime(3C)  for  information  regarding time value
39                             (time_t). Each line of output ends  with  isdst=1
40                             if  the  given  time  is Daylight Saving Time, or
41                             isdst=0 otherwise.
42
43
44       -c [loyear],hiyear    Cuts off the verbose output near the start of the
45                             given  year(s) . By default, the program cuts off
46                             verbose output near the start of the  years  -500
47                             and 2500.
