My application processes MsgType.REFRESH_RESP, MsgType.UPDATE_RESP(RespTypeNum=TRADE, QUOTE, UNSPECIFICED) for trade, quote and security status.

When i run the program overnight, the program receives the following message, the timestamp is Eastern time, so it is 3:55:00AM GMT time, this message is extracted for symbol HSBA.L. This message appears to signal a start of day to let application to clean up things OPEN_PRC, OFF_CLOSE, etc. However, I did not find any documentation for this, and our application supports EU, USA, CANADA regions, and I would like to know does this apply to all regions above. Also, I would like to have a more complete description of events so that we can decode the instrument status and market status through the whole day.
