epoch time format for logging
All,
For reasons of simplicity && consistency, I would like to have my logs
have epoch time (plus milliseconds) as their format. I figure:
1. this should be the most efficient way to get a timestamp
2. it is completely clear - unlike local time, or partial times (eg.
HH:MM:SS) there is no question of exactly when the event occurred.
3. it is concise - only taking 10 (or 14 with ms timestamp) characters.
4. it is exceedingly easy to do date arithmetic with it
5. it can searched as a number hence finding ranges in which events
occured in very large files is a simple, binary search.
Anyways, looking through the docs for log4j, I didn't see any docs on
how to do this. Is it possible, and if not currently possible, how
easy would it be to add it?
Again, I'd like to standardize all my logs on this, so any info on how
to do it is appreciated..
Thanks much,
Ed

I reworked the code in the date converter solution to be more OO. This is
now in SVN. Use %d{UNIX} and %d{UNIX_MILLIS}. I updated the manual in SVN
as well.

I create a JIRA to track possible solutions:
https://issues.apache.org/jira/browse/LOG4J2-415
I have attached two different solutions in a patch file.

Hello Ed,
This is what Log4j 2 can do now WRT to time stamp formatting:
https://logging.apache.org/log4j/2.x/manual/layouts.html#PatternLayout
When you say epoch time, do you mean simply that you would like to use the
result of java.lang.System.currentTimeMillis() ?
