Time getting reduced by 1 hour
I am setting TZ=EST5EDT,M3.2.0/02:00:00,M11.1.0/02:00:00
Then Setting the date to Mar 14 01:40 EST
date 0314014010
Sun Mar 14 01:40:36 EDT 2010
Note that it show it EST. According to my TZ variable 01:40 Should be in EST only.
On executing date command once again it shows
date
Sun Mar 14 00:42:09 EST 2010
Note that EDT changed to EST and 01:40 reduced to 00:42
Can you help why it is happening..
I am using AIX6.1
Thanks in Advanceee

The time is in the format of HM (HoursMinutes)
For example:

my problem is with the single-digit hours. If the time is 2200, I use this code:

zlacon.f
zlacon.f(3) LAPACK zlacon.f(3)
NAME
zlacon.f -
SYNOPSIS
Functions/Subroutines
subroutine zlacon (N, V, X, EST, KASE)
ZLACON
Function/Subroutine Documentation
subroutine zlacon (integerN, complex*16, dimension( n )V, complex*16, dimension( n )X, double precisionEST, integerKASE)
ZLACON
Purpose:
ZLACON 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*16 array, dimension (N)
On the final return, V = A*W, where EST = norm(V)/norm(W)
(W is not returned).
X
X is COMPLEX*16 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 ZLACON must be
re-called with all the other parameters unchanged.
EST
EST is DOUBLE PRECISION
On entry with KASE = 1 or 2 and JUMP = 3, EST should be
unchanged from the previous call to ZLACON.
On exit, EST is an estimate (a lower bound) for norm(A).
KASE
KASE is INTEGER
On the initial call to ZLACON, 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 ZLACON, KASE will again be 0.
