Re: N900 auto time update
 

I think the time settings on the N900 are badly broken. If I have a wrong date set then turn on automatic time settings nothing changes. fair enough, auto time doesn't work but if the time isn't set it seems as if I can't get a gps lock in ovi maps or weather info until I set the right date manually. what's with that?

Solution to N900 auto time update
 

NTP requires network and has
firewall/proxy/server-side issues.
.
Use your GPS ! :D
It works, even in the most remote place you can find.
It doesn't require you to have gprs or wifi access.
It doesn't need firewall pinholes or proxies.
And it does it very nicely.

GPS Recorder
GPS track logger to KML, GPX and/or CSV formats
Yet another GPS track logger.
Main features :
* Gathers as much information as possible from the GPS subsystem at a desired frequency (time, satellites, fix loss, etc...).
* Exports your saved tracks to KML/KMZ, GPX and/or CSV files in a single operation.
* Snap and name a position (POI) while recording to see it later on a map.

* Automatically updates system time according to GPS time.

What if we don't want to eat our batteries just for a time update?

Re: Solution to N900 auto time update
 

It only takes a few minutes to lock in,
then turn it off and you should be good for at least a day or two
(if you are trying to maintain 'informal' accuracy).
If you are after continuous millisecond accuracy then
maybe you need a different piece of hardware.
In that case even the NTP sync done through the variable latency
of a Wifi or GSM link is going to cause jitter.

GPS time is the very highest accuracy you can get in consumer goods - even NTP uses GPS as Stratum-Zero

HTH:)

Re: N900 auto time update
 

i need to run GPS recorder manually or does it leave a daemon running set to be launched automaticly on each boot?

Re: N900 auto time update
 

You mean when you reboot the n900?

Just run it when you actually need it - the gps eats batteries.
To run it daily or once a week maybe to tune your n900 timestamp
does not require more than a few minutes for the gps to lock in.

i suppose you could schedule a launch each day...
... not sure how you would turn it off automatically though.

Turning it on and then forgetting about it would flatten the battery.

Still in devel I note; any particular reasons it's not ready for prime-time yet?

Re: Solution to N900 auto time update
 

Hi,

I'm the developer of GPS Recorder.
Technically speaking, the application has been pushed into the extras-testing repository and is ready (version 0.1.152) to go to the 'extras' repository and replace the actual and very old version 0.1.112.

As for this version 0.1.152, no bug has been reported since its release in the 'extras-testing' repository but it needs 6 votes from the Maemo.org community (users, testers, developers) before it can be pushed into the 'extras' repository.

Since I do not talk too much about my application, there is not a huge amount of people who use it. So every time I push a new version into the extras-testing repository, it can take a while before it is actually released and visible to a wider range of users.

I recognize this community oriented releasing policy can be annoying sometimes and it actually can cause some headaches to the developers, but it is the way it works so it mainly depends on your votes ! :)

Cheers,
Jean-Charles

Re: N900 auto time update
 

some time ago i traveled from Europe too New Zealand, i landet in Dubai and Melbourn, so i passed many time-zones.
Everytime I switshed on the device it automatically updated the clock without any internet connection.
So for me it seams to update the time over the mobile-network.

Re: N900 auto time update
 

How important are the time settings? I noticed that the time set itself correctly when I first flashed the device to PR1.3.
Then the Battery fell out without a shutdown and now it asked me for the time. The time doesn't update automatically. If nothing is changed on the time settings menu and save is pressed the Internet doesn't work with 3G a lot like the A-GPS. can anybody give a technical reason for this?
