several GT06 chinese devices reporting odd time/date

Hello again.
I'm having a little bit of trouble with GT06 devices, they seem to be reporting any time and date but the correct one. (and i'm not meaning about timezone diferences related stuff)
I have 3 devices (on a sum of 4, the last one still not installed) that report diferent time and date also between them.

¿is this normal behavior?

I programmed them using copy and paste, so the whole lot of parameters went to all of them, even timezone.

This is a part of the server log showing what I mean.

I've marked lat and lon report are ok, but it also seems to be some error on speed since devices are stoped but they are reporting speed anyway, and also all of them something diferent.

Thanks in advance.

All of the samples are status messages that don't include any location data, so Traccar uses last known location (including time).

Ah, ok, thank you very much Anton.
