My time has not changed

[paskali]

Hi all, as well as a lot of you know, the last sunday of the october month the time in almost all europe countries have to be changed.
I have set my local tz variable as follow:

TZ='CET-1CEST,M3.5.0,M10.5.0/3'

I hoped the time makes update in automatic mode but it is not happened and i see yet the old time.

Why?

I tested your bootcode with the 5.0.2 iso, it correctly gave CET (UTC+1) time.

Make sure you don't have "noutc", and that the tz=blabla has tz in lower case.

I'm using "noutc" boot code plus the same time zone boot code (but lower case "tz=").
For me it did work as expected.

There is no differences between upper and lower case and i do not really want to set in UTC the date on my BIOS: simply it did not work. However i have noticed the change two days after.
Now i have to wait the next spring.

UTC time is required for Linux to be able to automatically move to DST and back.

Linux will change to and from DST when the HWCLOCK setting is set to `-u', i.e. when the hardware clock is set to UTC (which is closely related to GMT), regardless of whether Linux was running at the time DST is entered or left.

When the HWCLOCK setting is set to `--localtime', Linux will not adjust the time, operating under the assumption that your system may be a dual boot system at that time and that the other OS takes care of the DST switch. If that was not the case, the DST change needs to be made manually.

There is no problem for me to adjust manually the time however it is need to set tz as well i made to syncronize the clock with an ntp server:

Code: [Select]

sudo ntpclient -s -c 1 -h ntp1.inrim.it
sudo hwclock -w -l

Unlikely to be related to timezone issues, but "ro" is wrong, while "waitusb=0" appears meaningless.

Some time ago we have already talked about my bootcodes in this forum or elsewhere, i do not really want to explain one-by-one those are all right.

Please consider to talk only about the main question, discard the rest.

This is a public forum, and it is not difficult to observe that the proportion of not or to a small degree active users is rather high, while the proportion of guest visitors versus members may be even higher.

Therefore, whatever is articulated here should be done so with all potential readers in mind; hence I pointed out what I did even if it might not directly concern the main subject of the thread, while clearly stating that the questionable boot parameters would rather unlikely be at the cause of the latter.

Core is the first (and so far only) system with which daylight saving changes worked fully automagically - for 8 consecutive times by now, after configuring it in my bootloader once, inspired by this post:
