And in a some device device time and fix times shows diffrent in UI. I am in puzzule from few days please help me to set fix time as server time and ingore device time if it is possiable please guide me.
How to set server time as fix time? I am using SQL Server 2019 Database in a Windows VPS Server. Or, any other solution for me.

Please Help .. Please Help ...Please Help

Make sure your device reports UTC time to the server. The the time should be correct.

Thanks a lots Anton for your quick responce. My devices use GMT time zone but time is accurate our server UTC time.
I need to fix the server time as fix time if it is possibale and not effect any report or any other area. Today, I found your replay on a topic with:

<entry key='time.override'>serverTime</entry>
<entry key='time.protocols'>osmand,gt06</entry>

and I add these lines on traccar.xml after restarting the server, It shows server time device time and fix time same for some devices but in some devices having same protocol shows diffrent time on web UI.

What timezone do you have on the server and the client?

Server Time zone UTC +5:45 (Kathmadu) , and Client Time Zone Same as server . GT06 Devices having GMT +5:45 . In a above log:

2024-05-28 08:18:07  INFO: [T295055d8] id: 355488020118137, time: 2024-05-28 08:18:06, lat: 27.50407, lon: 83.45596, course: 112.0

This is correct time .

By client I mean your browser or mobile device.

GMT+0545 (Nepal Time)

OK, so the server and the client timezone is the same, you should see the same values in the app and in the logs.

Yes! In some case its correct data on my custom mobile app and traccar web UI, But In some devices when I check with SMS parameter it shows correct data on when it send data to the server diffrenct time . When I see in log its diffrent time than SMS replaied by device. After adding :

<entry key='time.override'>serverTime</entry>
<entry key='time.protocols'>osmand,gt06</entry>

I am geeting much accurate data in trip report.

Adding time override is not recommended. You should instead figure out the root cause for the issue.

Yes ! I got another error after override on playback and live view mess lines appers:

I cant understand please help. Device reporting correct time, server reporting correct time, our device and server in same time zone. Browser and mobile app aslo in same time zone. But , Fix time shows diffrent time. I have problem in Trip report due to this. When I used <entry key='time.override'>serverTime</entry>, <entry key='time.protocols'>osmand,gt06</entry> It prodcue accurate Trip Report but it create error on live view and playback.

Please Help Me !!!

How can I slove this Time problem ? Please someone help me . In gr8 Trouble.

First step - disable time override. Next - provide logs showing the problem. Make sure you include the full connection session from the word "connected". Session id is in square brackets.

I disable time override. I called device vender he suggest me to setup time zone as 0,0 so I configure the device GMT E +0,0 after doing this device report incorrect time in SMS Query , But I wonder how it is possiable in our traccar server web UI it shows correct time. I drive a car for test and shows correct time on trip report too.

Can I send log whole file as text file.
