The first number of each node is the time offset (see below).
The second number is the node id, this is the unique identifer for the wireless node.
All the numbers after the first two are data values. The first node here (node 16) has only one data value: 1137.
Optional offset and time parameters allow the sender to set the time
reference for the packets.
If none is specified, it is assumed that the last packet just arrived.
The time for the other packets is then calculated accordingly.
offset=-10 means the time of each packet is relative to [now -10 s].
time=1387730127 means the time of each packet is relative to 1387730127
(number of seconds since 1970-01-01 00:00:00 UTC)
Examples:
// legacy mode: 4 is 0, 2 is -2 and 0 is -4 seconds to now.
input/bulk.json?data=[[0,16,1137],[2,17,1437,3164],[4,19,1412,3077]]
// offset mode: -6 is -16 seconds to now.
input/bulk.json?data=[[-10,16,1137],[-8,17,1437,3164],[-6,19,1412,3077]]&offset=-10
// time mode: -6 is 1387730121
input/bulk.json?data=[[-10,16,1137],[-8,17,1437,3164],[-6,19,1412,3077]]&time=1387730127
