Russ updated LOG4J2-1978:
-------------------------
Description:
Rolled dated log files have the wrong date, in relation to the enclosed dated
log entries.
Rolled dated log file should mirror the date of the enclosed log entries.
Using the following example of a "daily rolling file" ...
* FilePattern: App_%d{yyyy-MM-dd}.log
* log entries for the date: (ie.) 2017-12-01 (note: the day is the 1st)
* are logged in base file named: (ie.) App_2017-12-01.log (note: the day is the
1st)
* The first occurrence of the roll should be midnight on the 2nd but that does
NOT occur
* Log file App_2017-12-01.log now contains log entries for both 2017-12-01 and
2017-12-02
* The second occurrence of the roll is on the 3rd, and does occur, however...
* Log file App_2017-12-02.log is now having log entries for 2017-12-03 written
to it
This occurs similarly at any level of granularity, of the date/time iteration.
For instance..
* with a FilePattern (focusing on the date pattern specifically) of:
%d{yyyy-MM-dd_HH-mm}
* log entries for: 2017-12-01_08-32
* will be in the rolled file: 2017-12-01_08-31
