Hello.

Each packet is first saved into internal memory and when it is sent is removed. Every record has Timestamp to identify when it was created:

To verify how many records have been generated since device start or reset you can use getinfo SMS/GPRS command:

SR - parameter in getinfo response is Number of Sent Records.

But if the FMB has not GPS Signal the timestamp from the package still valid? the counter is not a problem, but dont know if a package is from a buffer or real time is...

I have others models from others manufacturers and normally when the GPS Signal is off, the timestamp is complety wrong

I have some packages with the timestamp  2004-01-01 00:00:13

Hello.

It depends on device configuration:

Records Saving/Sending without TS setting:

Time synchronization - device has internal clock which can be synchronized over GNSS, GSM and NTP:

I recommend to use NTP Resync feature by setting value different from 0.
