When source_timestamp set for sample?

Hello.

I use Reliable Qos. I want to check probable latency in receiving data by dataReader. For this purpose when one data received by dataReader in "sampleInfo" I calculate difference between "source_timestamp" and "reception_timestamp". For accuracy I want to know:

Is "source_timestamp" time that I call write(the_sample) in DataWriter? Or it is time that sample published from dataWriter's queu to the network?

Identical source_timestamp through middleware
Hi,
 
I am currently testing to latency of a middleware program. This program is subscribed and recieves a
sample from a custom publisher and a specific topic, which contains various primitive Java types. After
receiving a sample, the program alters the data to the user's choice (the middleware is already expecting a
sample that fits a certain object).

I few questions regarding the relationship between the parameters in the sampleInfo struct and write_w_params (attached is the code I’m using).
