Don't have access to a Mac OS box anymore, but I can reproduce this under FreeBSD 7.2 and 8.2. It looks like the date command is substituting the current seconds into the value. When I run it close to a minute boundary, for one of your times, I get:
Where 'date executed' is the time I ran the command, 'from date' is the epoch time date returned, and 'what that is' is what the epoch time converts back into. Notice that the date, hours and minutes are all correct, but the seconds match the execution time.
Sounds like a bug in date to me.
You might try something like this which appends :00 to the time and then passes it to xargs.
EDIT: If it wasn't clear, /tmp/t was my file with the list of times.

When i was trying to store a file of size 743 MB into a directory i got a msg. that the disk is full. But when i used the df -k . command on that directory it showed only 40% in usage and the disk had more than enough memory for the file. When i checked the syslog i found that at that instant of...

The command ps -eaf gives inconsistent result when executed on XYZ server (the command shows 1, 2 or 3 instances of the process. Ideally it should show only 1).

Hi Guys,
Anyone who knows how to compare the current date with the a file containing a date, say for example I have a file that looks like this:

Hi,
I have a file that has inconsistently numbered columns.
Like row1 has 23 columns, and row 2 has 34 columns etc.
I would like to re-order the first 8 columns as required and from the 9th column till the end, I would like to print it as it is.
I tried to read the re-ordered 8 columns... (7 Replies)

clacon
clacon.f(3) LAPACK clacon.f(3)NAME
clacon.f -
SYNOPSIS
Functions/Subroutines
subroutine clacon (N, V, X, EST, KASE)
CLACON estimates the 1-norm of a square matrix, using reverse communication for evaluating matrix-vector products.
Function/Subroutine Documentation
subroutine clacon (integerN, complex, dimension( n )V, complex, dimension( n )X, realEST, integerKASE)
CLACON estimates the 1-norm of a square matrix, using reverse communication for evaluating matrix-vector products.
Purpose:
CLACON estimates the 1-norm of a square, complex matrix A.
Reverse communication is used for evaluating matrix-vector products.
Parameters:
N
N is INTEGER
The order of the matrix. N >= 1.
V
V is COMPLEX array, dimension (N)
On the final return, V = A*W, where EST = norm(V)/norm(W)
(W is not returned).
X
X is COMPLEX array, dimension (N)
On an intermediate return, X should be overwritten by
A * X, if KASE=1,
A**H * X, if KASE=2,
where A**H is the conjugate transpose of A, and CLACON must be
re-called with all the other parameters unchanged.
EST
EST is REAL
On entry with KASE = 1 or 2 and JUMP = 3, EST should be
unchanged from the previous call to CLACON.
On exit, EST is an estimate (a lower bound) for norm(A).
KASE
KASE is INTEGER
On the initial call to CLACON, KASE should be 0.
On an intermediate return, KASE will be 1 or 2, indicating
whether X should be overwritten by A * X or A**H * X.
On the final return from CLACON, KASE will again be 0.
