[gentoo-user] daylight savings time

[gentoo-user] daylight savings time

[Roger Mason]

Hello all,

My home province (Newfoundland & Labrador) has, in its infinite
wisdom, decided to adopt daylight savings time from 11 to 04 November,
rather than the more common dates in April & October.

Can someone tell me what I need to do to accommodate this change, if
anything?

Thanks,

Roger

Hm, set your hardware clock to UTC and do as root:

rm /etc/localtime
ln -s /usr/share/zoneinfo/Canada/Newfoundland /etc/localtime

should work...

http://en.wikipedia.org/wiki/Newfoundland_Standard_Time_Zone suggests
that it was changed just recently. Make sure your timezone-data ebuild
is up to date and installed. In order to get an 2007 version, you might
need to architecture unmask it.

http://www.twinsun.com/tz/tz-link.htm has wealth of information
regarding zoneinfo.

That's not how it's done anymore. Instead you set:

TIMEZONE="Canada/Newfoundland"

in /etc/conf.d/clock and: 

# rm /etc/localtime
# cp /usr/share/zoneinfo/Canada/Newfoundland /etc/localtime

This has the advantage that it'll work even when /usr isn't mounted.

TIMEZONE is used by the timezone-data ebuild, so emerge it and it'll 
automatically update /etc/localtime, no need to do it manually.

Running the following command will tell you how your current timezone is
set:

zdump -v /etc/localtime | grep 2007

For EST the result should look as follows:

ennis@bubba1-rep ~ $ zdump -v /etc/localtime | grep 2007
/etc/localtime  Sun Mar 11 06:59:59 2007 UTC = Sun Mar 11 01:59:59 2007
EST isdst=0
/etc/localtime  Sun Mar 11 07:00:00 2007 UTC = Sun Mar 11 03:00:00 2007
EDT isdst=1
/etc/localtime  Sun Nov  4 05:59:59 2007 UTC = Sun Nov  4 01:59:59 2007
EDT isdst=1
/etc/localtime  Sun Nov  4 06:00:00 2007 UTC = Sun Nov  4 01:00:00 2007

IIRC SMTP dictates CRLF.  Some broken clients don't adhere to that
however.

It dictates CRLF for commands and responses (and envelope
header).  IIRCT, It's mute on what the body contains.

[gentoo-user] Daylight savings time

[James]

Hello,

In my /etc/conf.d/clock file I have these relevant settings:
CLOCK="local"
TIMEZONE="America/New_York"
CLOCK_SYSTOHC="yes"

it's a dual boot (XP & gentoo) workstation.

I had to set the time manually to adjust for the 1 hour
shift. Shouldn't this be automatic?

What did I miss?

I don't know, but I'm surprised to hear about this.  I thought we all
figured it out last spring.  The gentoo clock stuff should have been
updated long ago.

However, M$ Windows may insist on changing the time on its own,
so you may find it happens twice.

I have heard that Windows expects the hardware clock to be in local
time, including daylight savings adjustments.  Presumably Windows
maintains it that way.

True. So you should go with "local" if the box is a dual boot one.

I guess you mean that in this timezone there was recently a shift
due to daylight saving time?

> Shouldn't this be automatic?

This question was recently discussed in the German forums.
Here is a summary:
Since you have CLOCK="local" this can only be automatic if your
computer was running during the shift - when you start your computer
after the shift, Linux will consider the hardware clock as the
correct (already shifted) time information.
If the shift happened with your setting although your computer was
not running, another program (typically: windows) has done the shifting.

Only if you run CLOCK=UTC the shift is guaranteed to work in any case
(of course, unless another program like windows interferes).

BTW: In case you use FAT, you might also want to consider the solution
proposed in
   http://forums.gentoo.org/viewtopic-t-579915.html
(which will make your hardwareclock also run with a constant offset to
utc i.e. the shift will also work reliable, but windows will display
the wrong time half of the year. However, the advantage is that
filestamps on FAT partitions will never change.)
