Where do these phones get there time from?

I remember setting them once around three years ago, when I installed
them, but not touched their time/date since.

Late yesterday evening, I spotted the time on the display was exactly 1
hour slow or behind, as if on BST. I made a mental note to check if
there might be a DST setting in the phone, but later today I noticed
the time was correct.

The only thing I can think of, is that that phone line has not been
rung since the change to GMT on Sunday. except it rang at 09:30 this
morning with a call. Maybe the incoming call corrected the clock?

I've never found that the time has corrected itself automatically. Certainly
when the hour changed recently the clock was still wrong even after I'd
received a phone call, so it looks as if the ringing signal and the caller
ID doesn't update the clock.

I've always had to correct the clock manually, both if it drifts slightly
and whenever the hour changes. It never occurred to me that it *might*
correct itself automatically: it's just one of the various clocks (eg
microwave, both our cars, DECT phone, SLR and compact cameras) that needs to
be corrected manually the morning after an hour change. The cameras have a
GMT/BST switch which applies exactly one hour change, but most need setting
from scratch; the cameras also really need setting from scratch because they
gain/lose slightly wrt a time source such as GPS/mobile phone, or NTP-synced
computer clock.

The time is carried with the alleged incoming phone number on the caller id
string sent before the first ring iirc

If on BT or an openreach provided line then

use the line test facility
Dial 17070
then dial 1 for ringback
clear down
wait for the ringback
clear down
Phone reset to correct time

The likes of a Sky provided exchange line won't have a customer accessible line
test number.


The caller ID spec is at

That's it then, thanks..

That assumes the phone is capable of re-synchronising its local clock with
the reference time in the caller ID. Based on other people's comments in
this thread, it sounds as if the phone *can* resync itself, so it's strange
I've never noticed this when the hour changes. I'll have to test it: set the
clock manually to a time that is wrong by a few minutes and then ring the
phone from my mobile to see if the clock changes its time to the correct
one. Is the clock-sync a feature that is always on, or does it have to be
enabled in a menu?

'Siemens' Gigasets ancient and modern don't seem to do at all, but in my
experience everything 'BT' branded fixed or cordless regardless of price point
has for many years done it by default and while you can manually set it there is
no option to disable this functionality.

I have a caller display unit of 15+ years vintage and that's exactly how
the time display works on this unit. Remove power and batteries and the
time is incorrect until the first incoming phone call. The same with
clock changes - the first incoming call will correct the time or else it
will remain an hour out.

Our Gigaset phones certainly change their time with GMT/BST. There's
a setting in the base station that tells it where to get its time from
if I remember right, a web NTP server.

In my phone's menu, all I could find was time/date manual settings and
24/12 hour display. No mention of auto update or a DST option.

I've just tried it: I manually set the time to a few minutes in the past and
then phoned my landline from my mobile. The time immediately changed to the
correct time. I've only had the phones 4 years, and I've never noticed
before that the time corrects when there's an incoming call. Next time the
hour changes I'll have to see whether it can cope with a larger change of 60
mins rather than a couple of mins - I wonder if there's any coding that
prevents very large corrections to the time.

It's a shame there was nothing in the instructions that I could see which
mentioned that the clock was resynchronised by caller ID, and that phoning
from a mobile might be an easier way of correcting the time.

Not necessarily. The Gigaset base station needs to be on a LAN to
enable it to be configured using its web configuration screens.
Assuming there is some system on the LAN that knows the time then it
can run an NTP server to provide the 'right' time to other systems on
the LAN.

Well, It would surely be out the other way if it had not been set, sounds to
me like somebody set it the wrong way. Spring forward, fall back.


The clocks that have auto summer winter have gone wrong this time. I have
two, a clock for the blind but free running, and a talking pendent clock.
Both have the auto switch on but did not change. On further investigation it
seems it may in fact change this coming weekend, as this year the US and the
UK change on different weekends for reasons best known to themselves, so if
they assume the dates will always agree, come Sunday morning both will be an
hour out the other way. Bah humbug.

All clocks, my mobile phone, my watch, PC's plus obviously now my
landline phones receives time syncs, that leaves just the microwave and
oven which need to be sorted manually by SWMBO, which she did without
comment. I was rather distracted at the weekend so to be honest, I
wasn't even aware the clocks changed. I did half notice that it was
lighter on a morning, but it still didn't sink in until I spotted my
landline phones were an hour out.

Must be just on the borderline. Ours is a C475IP and does know how to
talk NTP. We've had it a long time, my guess would be that it's older
than your C460IP.

As others have noted, BT seem to update the time on devices based on the
incoming call.

However, I occasionally look at the call logs on BT's Call Protect for
my BT landline, and I notice that the timestamp has not adjusted to the
clock change last w/e, but Mechanical Meg on 1471 does give the correct
timestamp.
