Configure gt06.timezone

So recap below on what worked. This should be added to GT06 device notes! This was super confusing.

Command to fix timezone vs SMS: GMT,E,0,0# (for EST)

Remove and add device in traccar to get rid of time "in future".

Add in traccar config files:

<entry key='filter.enable'>true</entry>
<entry key='filter.invalid'>true</entry>
<entry key='filter.zero'>true</entry>

Reset traccar service

Other notes:

Device updates heartbeat every 5 minutes when not moving. Heartbeats have 0,0 coordinates for GPS

Once the first position is detected during move, it will show on traccar map and will update position only during physical movement of GPS.

This is the lowest price 3G tracker on the market so far. Hopefully more come on the market soon.

Thanks for sharing the information.

is this still valid?

<entry key='filter.enable'>true</entry>
<entry key='filter.invalid'>true</entry>
<entry key='filter.zero'>true</entry>

I am try

<entry key='gt06.enable'>true</entry>
<entry key='gt06.port'>5023</entry>
<entry key='gt06.timezone'>-25200</entry>

gt06.timezone is deprecated

I would recommend to use decoder.timezone attribute on the device itself. Value is Java timezone name.

<entry key='decoder.timezone'>true</entry>

like that ?

As I said, it's device attribute, not configuration parameter.

can you give example or screenshoot ?

I think like this ?

<entry key='decoder.timezone'>Asia/Jakarta</entry>

Hi Anton,
In relation to this I'm running 4.2 linux server. I Have gt06 protocol based devices some have correct time based on the state vs my browser time and some are 8 hrs advanced. maybe due to the fact that I set the server time via traccar gui to asia manila. because of this inaccuracy. tried too use the parameter gt06 timezone set to 0. then restarted the service. upon checking those correct time were affected by the adjustment due to this, removed the config param. the correct time never came back. plus upon observation, the time did not move anymore. sorry for the lengthy message.

Please also check my logs:

2019-01-02 00:55:22  WARN: An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception. - Too many open files - IOException

Thank you.

All you need to do is configure device to report UTC time. Only if that's not possible, you should set gt06 timezone configuration. Don't change anything else. Nothing else affects time.

i'm having the same timezone problem. all route logs, are showing 8 hours ahead. i'm on GMT+8, my OS (windows) is on the correct time zone too, (08+00). i also viewing locally on my browser.

Thanks Anton went back to normanl again. Some still not uodating. I have not tried setting the timezone decice level. Will give an update once done. More power.

after following every instruction still my timezone shows GMT while I am on GMT+5.30 any help please
