[Quickfix-developers] Sending time question

[Victor G. <vic...@ch...>]

I have a question regarding the sending time in the header. 

When sending any message to a counter party, like the following:
<20050105-20:15:00, FIX.4.4:GATEWAY->ADAPTER, outgoing>
 
(8=FIX.4.4^9=74^35=0^34=34^49=ENLON00WK002^52=20050105-20:15:00.831^56=CTC_M
DAdapterEurex^10=162^)

Is the SendingTime (tag 52) the time the message is actually sent out, or is
it the time when it is placed on a queue, meaning there might be a lag
before the message actually goes out.

My concern is that I am noticing a lag between the time the heart-beat
messages goes out and the time it is received at the other end, which, at
times, causes the other side to logout/disconnect. This might be due to
network delay, but I want to be sure it is not something on my end.

I am using 1.9.4.

Thanks.
