Getting_setting_date and time on Edison

I have an active internet connection on the edsion, but when I enter 'date' I get a date and time that is over a week old. Why? Isn't the date and time always current?

Re: Getting_setting_date and time on Edison

not sure -

are you behind a proxy / firewall? do you use connman for network? (has a built-in lightweight ntp daemon)

Re: Getting_setting_date and time on Edison

thanks. no firewall that I know of. Isn't it possible to simply set the date using

$ date MMDDHHMMSS

??

Re: Getting_setting_date and time on Edison

sure - apart from the syntax would be slightly different (e.g. http://linux.die.net/man/1/date date(1): print/set system date/time - Linux man page).

And preferably via timedatectl

# timedatectl -h

timedatectl [OPTIONS...] COMMAND ...

Query or change system time and date settings.

-h --help Show this help message

--version Show package version

--no-pager Do not pipe output into a pager

--no-ask-password Do not prompt for password

-H --host=[USER@]HOST Operate on remote host

-M --machine=CONTAINER Operate on local container

--adjust-system-clock Adjust system clock when changing local RTC mode

Commands:

status Show current time settings

set-time TIME Set system time

set-timezone ZONE Set system time zone

list-timezones Show known time zones

set-local-rtc BOOL Control whether RTC is in local time

set-ntp BOOL Control whether NTP is enabled

However, the question why the date wouldn't be set automatically, right?

Re: Getting_setting_date and time on Edison

ok came across another long thread on this topic

so when I enter

$systemctl status systemd-timesyncd

I get

root@tesla:~# systemctl status systemd-timesyncd

Maybe try another time server?

Re: Getting_setting_date and time on Edison

Also if I enter

$timedatectl status

I notice that NTP synchronized: no

Local time: Mon 2015-03-09 20:31:47 UTC

Universal time: Mon 2015-03-09 20:31:47 UTC

RTC time: Sat 2000-01-01 00:24:02

Time zone: Universal (UTC, +0000)

NTP enabled: yes

NTP synchronized: no

RTC in local TZ: no

DST active: n/a

Re: Getting_setting_date and time on Edison

Ok narrowed the issue down to my edison configuration using connman to set a static IP.

If I revert back to default DHCP the time date is correct.

Can't seem to reach any time servers after setting a static IP using

$connmanctl config --ipv4 manual

Re: Getting_setting_date and time on Edison

you probably would need to manually set nameservers, default gateway ...

In connmanctl there are various settings:

(timeservers for connman internal time sync)

# connmanctl help

[...]

config Set service configuration options

--nameservers [] []

--timeservers [] [...]

[...]

--ipv4 off|dhcp|manual

[...]

In particular you should be able to ping a named address like "ping google.com"

if you install the connman-tests package you'd find some helpers which you might find of interest as well:

# /usr/lib/connman/test/test-clock

TimeUpdates = auto

Timezone = Europe/Paris

Timeservers = [ ]

TimezoneUpdates = auto

Time = 1426617841

# /usr/lib/connman/test/set-nameservers

Usage: /usr/lib/connman/test/set-nameservers [nameserver*]
