NAME
zdump - time zone dumper
SYNOPSIS
zdump [--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 routines 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 possible 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.
FILES
