Hi,

I have 2 extremly usefull, yet simple ideas for improvments in logging messages for slaves:

1. Hold at least one previous log file for slave
2. Include timestamp when logging messages in slave logs

Ad.1.
Currently if slave node disconnected for some reason, there is no way to diagnose why and when this occured, since old logs are lost - log file is wiped out.

Previous slave logs would help when diagnosing node disconnections.
This could be used as starting point for implementation:
https://github.com/jenkinsci/jenkins/blob/master/core/src/main/java/hudson/util/io/ReopenableRotatingFileOutputStream.java

Ad.2.
This should be added to all types of slave connections, ex. SSH, JNLP an so on.

Having this would make whole CI master-slaves infastructure based on Hudson more reliable and much easier to diagnose.
If for example slave is for some reason disconnecting at some fixed point in time, ex. at midnight there will be exact time of disconnection.
