the leading zero is indeed the problem.
too bad it's not past 1:00pm here.... otherwise i could help.
but you might try something like:
### Tue Apr 14 11:24:18 EDT 2009
set `date | sed -e 's/:/ /g'`
hours=$4
I think that doesn't have leading zeroes... More after 1:00 if solution isn't posted by then.

The date construct in UNIX can be used to calculate when something is finished: date -v+1H displays the time 1 hour from now.
I want to use the same construct in a script, but it is leading to error messages:

where $duration is calculated based on input... (3 Replies)

NAME
cposv.f -
SYNOPSIS
Functions/Subroutines
subroutine cposv (UPLO, N, NRHS, A, LDA, B, LDB, INFO)
CPOSV computes the solution to system of linear equations A * X = B for PO matrices
Function/Subroutine Documentation
subroutine cposv (characterUPLO, integerN, integerNRHS, complex, dimension( lda, * )A, integerLDA, complex, dimension( ldb, * )B, integerLDB,
integerINFO)
CPOSV computes the solution to system of linear equations A * X = B for PO matrices
Purpose:
CPOSV computes the solution to a complex system of linear equations
A * X = B,
where A is an N-by-N Hermitian positive definite matrix and X and B
are N-by-NRHS matrices.
The Cholesky decomposition is used to factor A as
A = U**H* U, if UPLO = 'U', or
A = L * L**H, if UPLO = 'L',
where U is an upper triangular matrix and L is a lower triangular
matrix. The factored form of A is then used to solve the system of
equations A * X = B.
Parameters:
UPLO
UPLO is CHARACTER*1
= 'U': Upper triangle of A is stored;
= 'L': Lower triangle of A is stored.
N
N is INTEGER
The number of linear equations, i.e., the order of the
matrix A. N >= 0.
NRHS
NRHS is INTEGER
The number of right hand sides, i.e., the number of columns
of the matrix B. NRHS >= 0.
A
A is COMPLEX array, dimension (LDA,N)
On entry, the Hermitian matrix A. If UPLO = 'U', the leading
N-by-N upper triangular part of A contains the upper
triangular part of the matrix A, and the strictly lower
triangular part of A is not referenced. If UPLO = 'L', the
leading N-by-N lower triangular part of A contains the lower
triangular part of the matrix A, and the strictly upper
triangular part of A is not referenced.
On exit, if INFO = 0, the factor U or L from the Cholesky
factorization A = U**H*U or A = L*L**H.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,N).
B
B is COMPLEX array, dimension (LDB,NRHS)
On entry, the N-by-NRHS right hand side matrix B.
On exit, if INFO = 0, the N-by-NRHS solution matrix X.
LDB
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,N).
INFO
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, the leading minor of order i of A is not
positive definite, so the factorization could not be
completed, and the solution has not been computed.
