zdump(1M) System Administration Commands zdump(1M)NAMEzdump - time zone dumper
SYNOPSISzdump [--version] [-v] [-c [loyear,]hiyear] [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 GMTO. This is consistent with the behavior of
the library calls; zdump reflects the same behavior of the time rou‐
tines in libc. See ctime(3C) and mktime(3C).
OPTIONS
The following options are supported:
--version Outputs version information and exits.
-v Displays the entire contents of the time zone
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 computing
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 otherwise.
-c [loyear],hiyear Cuts off the verbose output near the start of
the given year(s) . By default, the program
cuts off verbose output near the start of the
years -500 and 2500.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 An error occurred.
