wrong system time after reboot

[sprante]

I have the problem that the system time is not set correctly after a reboot.

In the /home/setup.sh script, the date and time should be taken from meteobridge.com with the following command sequence.

# get current date/time
echo "get date" >$SF
date -u -s "`wget -q -t 2 -T 7 -O - 'http://content.meteobridge.com/cgi-bin/utc.pl'`" >/dev/null 2>/dev/null
echo "read time from meteobridge server: `date`"

This does not work, however, in the log file /var/log/setup.log the date command in the last echo line returns a time from the past, possibly weeks or months old (apparently the time of the last reboot before the current reboot).

Here are the first seven lines in /var/log/setup.log

### setup.sh
Hardware: RPI3
LED path: /sys/class/leds/led1
Reseller:
Command failed: Not found
read time from meteobridge server: Fri Jul 7 22:26:08 CEST 2021
get IP tracker information.

Maybe the "Command failed: Not found" in front of the line "read time from meteobridge server ..." has something to do with it?

My meteobridge installation:
Plattform: Raspberry Pi 3 Model B+
SW-Version: Meteobridge 5.1 (Jul 8 2021, build 2188)

Is it constantly not working or just a singular glitch?
May be the connection to the Meteobridge server failed and by that no date update can be applied?

[sprante]

The error occurs reliably with every reboot.

If I log in as root immediately after the reboot, the date command with the wget call is executed on the shell without problems and the system time is set correctly.

I tried to analyze the problem further by adding additional echo messages to the /home/setup.sh script. But the changed script is overwritten with the original script when the system is restarted.

Hi
I've the same behavior
I set the Date is shell
reboot
and the date is drifted 2 days in the past with a wrong time also

Do we have an ntpd running ?

we should ntpdate after the boot and sync ntpd

here is my /var/log/setup.log now 16 august 2021 15:35

Just tested on RPI 3b, RPI 3b+ and RPI 4 and works fine on both. Please remember that it needs a reboot when having changed time zone.

[admin]

Are you going through a proxy?

[admin]

Just released update will make it through any existing proxy, forcing to get fresh data.

[jpouyaud]

hello
no proxy used here.
I will made some other test, one of the test worked yesterday, the RPI is now with the good time

[admin]

I made a change that when requesting the current date/time from Meteobridge server via HTTP the URL also includes an additional random pattern that will force any proxy in between to really ask the Meteobridge server and not present a former reply from the proxy cache.

Hi

I'm still impacted by this problem

today, I've rebooted my raspberry, and the system date was set to Tue Aug 24 2021

we have a big probleme here..


It's took me the day to discover this

so the metobridge has ruined my collection data for 21 august 2021

come on. we should stop with this buggy script and just follow best practive (ntpdate and ntpd )

[jpouyaud]

this is my /var/log/setup.log just after a reboot right now

also, after 3 reboot, 1 was a big fail with the Rpi not booting at all

### setup.sh
cat: can't open '/var/TZ': No such file or directory
Hardware: RPI3
LED path: /sys/class/leds/led1
Reseller:

ok looks like the date of 24 august correspond to my last backup DB and reboot...
annoying,
that means I've no data in backup

[jpouyaud]

Hi
here some more info which would help to solve this very annoying bug

I'm experiencing some small improvement by adding a delay of 1 minute for start boot

now the date is the right one, but the time is 5 to 15 minute in the past, a drift of 15 minute in other word

here is the log
### setup.sh
cat: can't open '/var/TZ': No such file or directory

Maybe the prb is with the head command which return an error ?

Like @sprante, if I run the command date -u -s "`wget -q -t 2 -T 7 -O - http://content.meteobridge.com/cgi-bin/utc.pl?rand=$RAN
DOM`" the date is well changed...

Hi

would be great to have some support here

the reboot is not safe with RPI and will not correctly preserve the time/date

thanks
