ZDUMP(8) BSD System Manager's Manual ZDUMP(8)NAME
zdump -- timezone dumper
SYNOPSIS
zdump [--version] [-v] [-c [loyear,]hiyear] [zonename ...]
DESCRIPTION
The zdump utility prints the current time in each zonename named on the command line.
The following options are available:
--version
Output version information and exit.
-v For each zonename on the command line, print 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 detected time discontinuity, the time at one day less than the high-
est possible time value, and the time at the highest possible time value, Each line ends with isdst=1 if the given time is Daylight
Saving Time or isdst=0 otherwise.
-c loyear,hiyear
Cut off verbose output near the start of the given year(s). By default, the program cuts off verbose output near the starts of the
years -500 and 2500.
LIMITATIONS
The -v option may not be used on systems with floating-point time_t values that are neither float nor double.
Time discontinuities are found by sampling the results returned by localtime at twelve-hour intervals. This works in all real-world cases;
one can construct artificial time zones for which this fails.

I am trying to issue the time command on a program so I can see execution times but it is returning all zeroes. Like this:
time pdriver arg1 arg2
0.000u 0.000s 0:00.00 0.0% 0+0k 0+0io 0pf+0w
"0+0k 0+0io 0pf+0w" --> The "0+0io" may change sometimes to a different number.
How can I run the... (2 Replies)
