[Openbts-discuss] Bogus timestamp from JSONEventsClient

[Simon P. <sim...@st...>]

Hi I'm using JSONEventsClient to get physical measurements from OpenBTS but
I don't know how to interpret the timestamps I get. To me it seems to be an
overflow, is there anyone who has an idea what might cause this?

This is what my measurements look like:

{
"data" : {
"burst" : {
"RSSI" : -34.0095,
"RSSP" : -6.00945,
"actualMSPower" : 5,
"actualMSTimingAdvance" : 0,
"timingError" : -1.04978
},
"channel" : {
"ARFCN" : 120,
"IMSI" : "240078585304473",
"carrierNumber" : 0,
"timeslotNumber" : 1,
"typeAndOffset" : "TCH/F",
"uplinkFrameErrorRate" : 0.0585415
},
"reports" : {
"neighboringCells" : [],
"servingCell" : {
"RXLEVEL_FULL_dBm" : -48,
"RXLEVEL_SUB_dBm" : -48,
"RXQUALITY_FULL_BER" : 0.0028,
"RXQUALITY_SUB_BER" : 0
}
}
},
"name" : "PhysicalStatus",
"timestamp" : "18446744072250882950",
"version" : "0.1"
}

The timestamp on the measurement is as you can see 18446744072250882950,
and the associated UNIX time is 1458830211.

Thanks for any help
