19 The \fBzdump\fR command prints the current time for each time zone
20 (\fIzonename\fR) listed on the command line. Specify \fIzonename\fR as the name
21 of the time zone database file relative to \fB/usr/share/lib/zoneinfo\fR.
24 Specifying an invalid time zone (\fIzonename\fR) to \fBzdump\fR does not return
25 an error, rather \fBzdump\fR uses \fBGMTO.\fR This is consistent with the
26 behavior of the library calls; \fBzdump\fR reflects the same behavior of the
27 time routines in \fBlibc\fR. See \fBctime\fR(3C) and \fBmktime\fR(3C).
31 The following options are supported:
35 \fB\fB--\fR\fIversion\fR\fR
38 Outputs version information and exits.
47 Displays the entire contents of the time zone database file for \fIzonename\fR.
48 Prints the time at the lowest possible time value; the time one day after the
49 lowest possible time value; the times both one second before and exactly at
50 each time at which the rules for computing local time change; the time at the
51 highest possible time value; and the time at one day less than the highest
52 possible time value. See \fBmktime\fR(3C) and \fBctime\fR(3C) for information
53 regarding time value (\fBtime_t\fR). Each line of output ends with
54 \fBisdst=1\fR if the given time is Daylight Saving Time, or \fBisdst=0\fR
61 \fB\fB-c\fR [\fIloyear\fR],\fIhiyear\fR\fR
64 Cuts off the verbose output near the start of the given year(s) . By default,
65 the program cuts off verbose output near the start of the years -500 and 2500.
71 The following exit values are returned:
78 Successful completion.
