Daylight savings time
.
On 11/6/11, my Knoppix 6.7.1 LiveUSB seemed to require adding ntpdate to provide
the correct transition from daylight-savings to standard time via internet access to NTP.
The other settings which without ntpdate seemed all right for Eastern US time until
this Sunday were as follows:
My hardware clock is set to local time; in /etc/default/rcS, 'UTC=no' is set; and in
/mnt-system/boot/syslinux/syslinux.conf, kernel option is set to 'tz=America/New_York'.
I've not changed any of these settings, only added ntpdate via Synaptic.
I think I've found that booting up Windows 7 on the same computer after the time change
has occurred has the same effect, without requiring the addition of ntpdate.

Only installing ntpdate via synaptic is of no use.
You have to run ntpdate either manually or in a cron-job. And it is very important, which parameter you use for ntpdate.
In an earlier posting I mentioned, you will run in trouble with dualboot installation of Linux and Windows, if your BIOS clock isn't UTC.

Hi, Werner.
Nice to hear from you.
I was and am surprised at how compatible ntpdate is with Windows 7
with the configuration I have described.
If I were dual booting more often,
I might have imagined that ntpdate was unnecessary.
As it is the effective appearance is:
If Windows has 'updated the hardware clock', ntpdate does nothing;
If Windows hasn't 'updated the hardware clock', then ntpdate does so.
I know the Linux standard is UTC. I still prefer local time.
I think I now have identified all the pieces that go together
to make that happen consistently.

Which parameter do you use with "ntpdate" and how do you start it:
manually or via cron-job?

Hi, Werner.
I have just accepted the default /etc/default/ntpdate, which is:
Code:
# The settings in this file are used by the program ntpdate-debian, but not
# by the upstream program ntpdate.
# Set to "yes" to take the server list from /etc/ntp.conf, from package ntp,
# so you only have to keep it in one place.
NTPDATE_USE_NTP_CONF=yes
# List of NTP servers to use (Separate multiple servers with spaces.)
# Not used if NTPDATE_USE_NTP_CONF is yes.
NTPSERVERS="0.debian.pool.ntp.org 1.debian.pool.ntp.org 2.debian.pool.ntp.org 3.debian.pool.ntp.org"
# Additional options to pass to ntpdate
NTPOPTIONS=""
It may be noted that there is no file /etc/ntp.conf in my /etc.
knoppix@Microknoppix:~$ less /etc/services | grep ntp
nntp 119/tcp readnews untp # USENET News Transfer Protocol
ntp 123/tcp
ntp 123/udp # Network Time Protocol
nntps 563/tcp snntp # NNTP over SSL
nntps 563/udp snntp
knoppix@Microknoppix:~$
Also, I do NOT also have ntp itself installed.

ps: Werner, this may be what you are looking for:
/var/log/dpkg/info/ntpdate.conffiles:
/etc/network/if-up.d/ntpdate
/etc/logcheck/ignore.d.server/ntpdate
/etc/dhcp/dhclient-exit-hooks.d/ntpdate
/etc/default/ntpdate
There is indeed an executable file ntpdate in /etc/if-up.d,
and that's the way it seems to work: within one minute of
getting wifi on-line, a time correction is made.

I was having this usual problem of mine also setting up Mint 11 LXDE,
To cure the local time problem, per Mint forum:
sudo apt-get install gnome-time-admin, then
System Tools>Time>Zone>America/New_York, in my case.
This works on Mint 11; it's worth a try here.

ps
I've tried this via Synaptic and concluded that Knoppix
doesn't have enough gnome infrastructure to run gnome-time-admin, unfortunately.
