How to add time pattern in the log when using java logger

We use java.util.logging, and we use java.util.logging.FileHandler to config the rotated logs.

We want to add timestamp into log file name pattern to make it looks like:

logFile_2011-08-25_14_*02*_38_PDT.0.log
logFile_2011-08-25_14_*12*_38_PDT.1.log
logFile_2011-08-25_14_*22*_38_PDT.2.log
logFile_2011-08-25_14_*32*_38_PDT.3.log

Be aware of the different timestamp in the log file name.

We are now using the pattern = "logfile_XXXXXX.%g"

No, java.util.logging no! Check out LogBack instead! It's a successor of log4j and of course implements sfl4j.

Back to your question, I'm not an expert of Java Logging but I believe you cannot do this through configuration. There might be other ways though..
