clients supporting the version of ADC that has this MSG field should be able 
to understand such a MSG and display the timestamp they were given instead 
of making up their own. the field is optional, so they don't have to add it 
to every outgoing message; they can choose to if they want to get fancy.
also, using this to measure the lag isn't what this was intended for, but if 
a client wants to use it for that purpose, no problem...

indeed, normal clients won't add this field to any of their messages; they 
should simply be able to treat incoming messages that have a TS param 
accordingly.

as for the use case, i have a bot that logs messages for me when i am not 
online, and when that bot forwards messages it has been logging back to me, 
i receive all messages as though they just got written, although some might 
be dating from a week ago. therefore, i want my bot to add a TS field to 
each message specifying when it was sent, so that when DC++ receives it, it 
displays it with its original timestamp.

another similar example would be a hub that offers an "offline PM" 
functionality: send a message to a regged user, and if that user is not 
online, the hub logs it and wait for that user to come back to send her your 
message. in this case too, the lag is not negligible anymore and there needs 
to be a way for the sender of the logged message (be it a hub or a bot) to 
tell when the message was originally sent.
